RESUMEN El liposarcoma es un tumor de origen mesenquimal que se presenta comúnmente en el retroperitoneo; es de crecimiento lento y su capacidad de producir metástasis depende de su tipo histológico. Este trabajo tiene como propósito presentar un caso de liposarcomas paratesticulares simultáneos con diferentes tipos histológicos, en un paciente masculino, de 80 años con antecedentes de salud y nivel socioeconómico bajo que venía presentando desde hacía dos años aumento de volumen en la región inguinal izquierda y testículo ipsilateral, al inicio fue indoloro; luego, a medida que aumentó de tamaño se tornó doloroso, abarcando la región inguinoescrotal derecha en su totalidad. El examen físico, incluido el signo de la transiluminación fue negativo. El estudio analítico mostró solamente velocidad de sedimentación globular en 95 mm/h y la LDH en 650 U/l; la ecografía testicular mostró una masa heterogénea, solida e hiperecoica, de aspecto graso inguinoescrotal y de más de 30 cm, sin llegarse a observar el testículo. Se realizó exéresis tumoral encontrándose tres tumores liposarcomatosos, dos de ellos con características histopatológicas similares y el otro con patrón histológico diferente. Luego del tratamiento quirúrgico el paciente se recuperó satisfactoriamente y no ha presentado recidiva según los controles periódicos realizados. Se consideró la publicación del caso pues los liposarcomas pueden llegar a confundirse a la exploración clínica con la presencia de una hernia inguinal de contenido graso con sintomatología similar a estas; por lo que debe hacerse una exploración clínica exhaustiva para realizar un correcto diagnóstico. El estudio histopatológico confirmó el diagnóstico de la enfermedad que, además, reveló la presencia de tres tumores liposarcomatosos y dos variantes histopatológicas del mismo, de lo cual no se encontraron reportes en la literatura revisada.

ABSTRACT Liposarcoma is a mesenchymal origin tumor that commonly occurs in the retroperitoneum; It is slow growing and its ability to produce metastasis depends on its histological type. The purpose of this work is to present a case of simultaneous paratesticular liposarcomas with different histological types, in an 80-years-old male patient with a health history and low socioeconomic level; For two years he had been experiencing an increase in volume in the left inguinal region and ipsilateral testicle, which at first was painless; Then, as it increased in size, it became painful, covering the entire right inguinoscrotal region. Physical examination, including transillumination sign, was negative. The analytical study only showed erythrocyte sedimentation rate at 95 mm/h and LDH at 650 U/l; The testicular ultrasound showed heterogeneous, solid and hyperechoic mass, with a fatty inguinoscrotal appearance and measuring more tan 30 cm, without the testicle being observed. Tumor excision was performed and three liposarcomatous tumors were found, two of them with similar histopathological characteristics and the other with a different histological pattern. After the surgical treatment, the patient recovered satisfactorily and has not had a recurrence according to the periodic controls carried out. The publication of the case was considered because liposarcomas can be confused on clinical examination with the presence of an inguinal hernia with fatty content with symptoms similar to these; Therefore, a thorough clinical examination must be performed to make a correct diagnosis. The histopathological study confirmed the diagnosis of the disease; which, in addition, revealed the presence of three liposarcomatous tumors and two histopathological variants of the same, from which no reports were found in the reviewed literature.

RESUMEN La elefantiasis escrotal es una condición que ha sido históricamente descripta en áreas endémicas de filariasis, pero es menos frecuente su presentación idiopática o asociada a otras entidades. Presentamos un caso de elefantiasis escrotal gigante de causa adquirida idiopática, al que se le practicó la exéresis de la estructura linfedematosa y la reconstrucción del defecto con colgajos locales y autoinjerto cutáneo. El motivo de su divulgación radica en que se trata de un caso muy poco frecuente, ya sea por la baja incidencia y etiología, así como por la importante magnitud del problema para el individuo. El objetivo principal en el tratamiento del linfedema, en el caso presentado, fue devolverle al paciente funciones primarias y elementales de vida, además de disminuir la morbilidad y otorgarle una mejor calidad de vida.

ABSTRACT Scrotal elephantiasis is a condition that has been historically described in areas where filariasis is endemic, but idiopathic cases or those associated with other entities are rare. We report a case of a patient with idiopathic acquired giant scrotal elephantiasis who underwent excision of the lymphedematous structure and reconstruction of the defect with local flaps and skin autograft. The reason for this presentation is the uncommon nature of the case due to its low incidence, rare etiology and the magnitude of the problem experienced by the patient. The main goal in the treatment of lymphedema in this case was to restore primary and elementary functions of life to the patient, reduce morbidity and provide him with a better quality of life.

ABSTRACT Defects in the scrotal region are caused in most cases by Fournier's gangrene, and sometimes by trauma or oncological pathologies. These wounds generate difficulties for the development of a normal life; They usually produce pain; the testicles are unprotected and spermatogenesis can be altered. Currently there is no standard method of scrotal reconstruction, and the techniques traditionally used do not offer functional or aesthetic coverage. They generally produce a big bulge in the genital region, which can make it hard to move the legs and wear pants. A surgical option is exposed to reconstruct the scrotum, by means of the bilateral gracilis muscle pedicled flap and split-thickness skin graft. For this purpose, a clinical case of a 64-year-old patient with sequelae in the perineal region, after Fournier's gangrene, is presented. The patient presented a total loss of the scrotum and exposure of both testicles. The method mentioned above is a valid option to reconstruct the scrotum and the technique used is described in detail, where it can be seen that it is easy to reproduce by a trained plastic surgeon.

RESUMEN Los defectos en la región escrotal son producidos en la mayoría de los casos por la gangrena de Fournier, y en ocasiones por traumatismo o patologías oncológicas. Estas heridas generan mucha dificultad para el desarrollo de una vida normal a los pacientes que lo padecen; por lo general producen dolor, los testículos quedan desprotegidos y la espermatogénesis puede verse alterada. Actualmente no existe un método estándar de reconstrucción escrotal, y las técnicas tradicionalmente utilizadas no ofrecen una cobertura funcional ni estética. Generalmente producen mucho abultamiento en la región genital, que puede dificultar el movimiento de las piernas y el uso de pantalones. En este trabajo se expone una opción quirúrgica para reconstruir el escroto, por medio del colgajo pediculado de músculo gracilis bilateral e injerto de piel parcial. Para tal efecto, se presenta un caso clínico de un paciente de 64 años con secuelas en la región perineal, posterior a una gangrena de Fournier. El paciente presentaba una pérdida total del escroto y exposición de ambos testículos. El método arriba mencionado es una opción válida para reconstruir el escroto y en este trabajo se describe la técnica empleada de forma detallada, donde se puede apreciar que presenta escasas complicaciones y es fácil de reproducir por un cirujano plástico entrenado.

Abstract We report a case of Fournier's gangrene rescued by debridement. A 40-year-old male patient had a 2x2 cm draining ulcer and 1x2 cm necrotic area in the scrotum for about a month. The patient was diagnosed with Fournier's gangrene. Septic shock and disseminated intravascular coagulation were absent. Computed tomography scan showed soft tissue gas in the scrotum but no gas in the retroperitoneal space or abdominal wall. Debridement was performed. Gangrene of the scrotum and necrosis of the testicle was also seen. Rothia dentocariosa was isolated in extracted wound cultures. He was saved after debridement and administration of strong antibiotics. This is the first case of Fournier's gangrene caused by R. dentocariosa in the available literature.

Resumen Presentamos un caso de gangrena de Fournier rescatado mediante desbridamiento. Un paciente varón de 40 años presentó una úlcera supurante de 2x2 cm y un área necrótica de 1x2 cm en el escroto durante aproximadamente un mes. El paciente fue diagnosticado con gangrena de Fournier. El shock séptico y la coagulación intravascular diseminada estaban ausentes. La tomografía computarizada mostró gas en los tejidos blandos del escroto, pero no en el espacio retroperitoneal ni en la pared abdominal. Se realizó desbridamiento. También se observó gangrena del escroto y necrosis del testículo. Se aisló Rothia dentocariosa en cultivos extraídos de heridas. Se salvó después del desbridamiento y la administración de antibióticos fuertes. Este es el primer caso de gangrena de Fournier por R. dentocariosa en la literatura disponible.

Abstract: Introduction: The classic clinical manifestations of inmunoglobulin A (IgA) vasculitis are palpable purpura without thrombocytopenia, arthritis, abdominal pain, and kidney injury, however, around 10% of patients may present scrotal manifestations. Case report: We report the case of a 4-year-old male patient who presented to the emergency room for pain in the scrotum, five days previously with the presence of dermal lesions in both lower extremities and mild abdominal pain, on physical examination found pain on palpation of the left testicle, absence of ipsilateral cremasteric reflex, erythema and swelling in both scrotums, testicular ultrasound was performed showing bilateral intratesticular and peritesticular vasculature with data of an acute scrotal inflammatory process. Given the clinically palpable purpura and abdominal pain, a diagnosis of IgA vasculitis with scrotal manifestations was integrated, according to what is referred to in the literature, it was decided to start treatment with a systemic steroid (methylprednisol 1 mg/kg/day), with the resolution of the condition in 48 hours. Conclusions: In the literature, cases of scrotal manifestations associated with the diagnosis of IgA vasculitis are reported, generally unilaterally treated habitually with steroids, there are no published data on the long-term prognosis of patients who presented with this manifestation.

Resumen: Introducción: Las manifestaciones clásicas de vasculitis por inmunoglobulina A (IgA) son púrpura palpable sin trombocitopenia, artritis, dolor abdominal y lesión renal; sin embargo, alrededor de 10% de pacientes pueden presentar manifestaciones testiculares. Caso clínico: Se describe el caso de paciente masculino de cuatro años de edad que acude a urgencias por dolor en escroto, dolor a la palpación de testículo izquierdo, ausencia de reflejo cremasteriano, eritema y tumefacción en ambos escrotos. Se realiza ultrasonido testicular evidenciando vasculatura intratesticular y peritesticular bilateral con datos de proceso inflamatorio agudo. Ante la presencia inicial de púrpura palpable y dolor abdominal difuso se integró diagnóstico de vasculitis por IgA con manifestaciones escrotales. Se decidió iniciar tratamiento con esteroide sistémico (prednisolona 1 mg/kg/día), con resolución del cuadro en 48 horas. Conclusiones: En la literatura se reportan casos de manifestaciones escrotales asociados al diagnóstico de vasculitis por IgA, por lo general de forma unilateral tratados habitualmente con esteroide, no existen datos publicados sobre el pronóstico a largo plazo de los pacientes que cursaron con esta manifestación.

ABSTRACT Introduction: Fournier’s gangrene is a polybacterial infection, usually caused by anaerobic and aerobic bacteria, characterized by scrotal and perineal necrotizing fasciitis. Its treatment is based on surgical intervention by excision of the necrotic area and early antibiotic therapy. There are several strategies to reconstruct the defect resulting from debridement, and it should be noted that tissue losses greater than 50% are usually reconstructed with flaps. Methods: Retrospective analysis of the series of cases of scrotal reconstruction after Fournier’s gangrene performed by the authors throughout 2020, totaling eight patients. Results: The most used flap was thigh fasciocutaneous flap, which presented a partial necrosis rate of 14.29%, without total necrosis. In one of the cases, it was possible to reconstruct a spongy urethra with gracilis muscle without fistulization, preventing the patient from undergoing a definitive urethrostomy. As for complications, the occurrence of minor complications that required simple revision procedures was common. The prevalence of 75% of diabetes mellitus in our series is highlighted, which may have negatively interfered with the healing process. Conclusion: Scrotal reconstruction with flaps is important to accelerate wound healing from Fournier gangrene debridement and to maintain the pouch aspect necessary for testicular thermoregulation. Our primary option was thigh fasciocutaneous flap, which proved to be safe. And minor complications were frequent in this series, without compromising the final result.

RESUMO Introdução: Gangrena de Fournier é uma infecção polibacteriana, geralmente causada por bactérias anaeróbias e aeróbias, sendo caracterizada por fasciite necrosante escrotal e perineal. Seu tratamento é embasado em intervenção cirúrgica com excisão da área necrótica e antibioticoterapia precoces. Diversas são as estratégias de reconstrução do defeito resultante do desbridamento, devendo ser salientado que perdas teciduais maiores do que 50% costumam ser reconstruídas com retalhos. Métodos: Análise retrospectiva da série de casos de reconstrução escrotal após gangrena de Fournier procedidos pelos autores ao longo de 2020, totalizando oito pacientes. Resultados: O retalho mais utilizado foi o fasciocutâneo de coxa, que apresentou taxa de necrose parcial de 14,29%, sem necrose total. Em um dos casos foi possível reconstruir uma uretra esponjosa com músculo grácil sem fistulização, evitando que o paciente fosse submetido a uma uretrostomia definitiva. Quanto às complicações, foi comum a ocorrência de intercorrências menores que necessitaram de procedimentos revisionais simples. Destaca-se a prevalência de 75% de diabetes mellitus em nossa casuística, o que pode ter interferido negativamente no processo cicatricial. Conclusão: A reconstrução escrotal com retalhos é importante para acelerar a cicatrização da ferida proveniente do desbridamento de gangrena de Fournier e para manter o aspecto de bolsa necessário para a termorregulação do testículo. Nossa opção primária foi o retalho fasciocutâneo de coxa, que se mostrou seguro. Pequenas intercorrências foram frequentes nesta série, sem comprometimento do resultado final.

Abstract: Introduction: genital trauma by firearm is a rare event. Case presentation: a 14-year-old male patient was seen in the emergency department due to moderate bleeding secondary to injuries to the scrotum and penis, caused by gunshot trauma. In the evaluation, the complete loss of the right testicle was observed, as well as damage to the left testicle in more than 70%. In addition, the scrotal and penile skin were partially lost. Treatment was surgical immediately on admission to the hospital, and the patient had a satisfactory postoperative evolution. Conclusions: management of gunshot genital trauma is a urological emergency. Assessment of the severity of the lesions is required, to grant the appropriate surgical treatment.

Se dio tratamiento quirúrgico inmediatamente al ingreso al hospital. La evolución postoperatoria sin complicaciones. Conclusiones: el manejo del trauma genital por arma de fuego constituye una urgencia urológica. Se requiere evaluación de la gravedad de las lesiones, a fin de otorgar el tratamiento quirúrgico apropiado.

ABSTRACT Background: Fournier's gangrene is a serious polymicrobial infection caused by microorganisms that act synergistically and determine a progressive necrotizing fasciitis in the scrotum and perineum with manifestations of sepsis that can progress to septic shock and organ failure. Objective: to characterize clinically and epidemiologically Fournier's gangrene in patients diagnosed in a reference hospital unit. Methods: retrospective, observational and descriptive study based on the analysis of the clinical records of 64 male patients with Fournier's gangrene, diagnosed at the Hospital Militar Principal/Instituto Superior de Luanda, Republic of Angola from January 2016 to December 2020. Study variables were: age, toxic habits, comorbidity, clinical manifestations, extension, location as well as its evolution. The quantitative variables were expressed as means, median and range, while the qualitative variables were expressed in terms of absolute numbers and percentages. Results: the average age was 45.09 years; 36 patients (56.2%) consume alcoholic drink and 14 (21.87%) declared smoking habits. The main comorbidity was diabetes mellitus in 21 (32.8%). Pain with increased scrotal volume predominated in 43 (67.2%) subjects; early surgical debridement with antibiotic therapy was the key to management. Five patients died. Conclusions: Fourner's gangrene is a serious disease that can present systemic repercussions and death. The cornerstone of treatment is early surgical debridement supported by support measures. The series presented showed adequate and effective multidisciplinary management.

ABSTRACT Acute scrotum syndrome is a surgical emergency, which if an adequate evolution is not made and there are delays in the diagnosis, the patient can have irreversible damage in the testicular viability. The Clinical Practice Guidelines on acute scrotum syndrome is presented with the aim of updating the subject and providing a care and teaching instrument in the pediatric surgery services of the country. Several diseases can be the cause of the onset of acute scrotum syndrome, including testicular torsion, testicular hydatid torsion, and orchiepididymitis. The fundamental symptom is testicular pain and usually requires surgical treatment. The timely treatment of these patients avoids complications such as the need for orchiectomy, sterility, and that way the patient is more quickly reincorporated into his social activity.

RESUMEN El síndrome de escroto agudo es una urgencia quirúrgica, que si no se hace una evolución adecuada y existen demoras en el diagnostico puede el paciente tener daños irreversibles en la viabilidad testicular. Se presenta la Guía de Práctica Clínica sobre el síndrome de escroto agudo con el objetivo de hacer una actualización sobre el tema y proporcionar un instrumento asistencial y docente en los servicios de cirugía pediátrica del país. Varias enfermedades pueden ser la causa de aparición del síndrome de escroto agudo, entre ellas, la torsión testicular, la torsión de hidátides testiculares y la orquiepididimitis. El síntoma fundamental es el dolor testicular y requiere generalmente tratamiento quirúrgico. El tratamiento oportuno de estos pacientes evita complicaciones como la necesidad de orquiectomia, la esterilidad y reincorpora más rápidamente al paciente a su actividad social.

RESUMO Introdução: O pênis é uma importante estrutura do corpo masculino, sendo sua reconstrução um desafio. Existem diversas doenças e deformidades que acometem este órgão, sendo necessário, em certos casos, a reconstrução total da cobertura cutânea do pênis, tendo já sido descritas na literatura diversas técnicas, tais como o uso de enxertos totais, retalho escrotal, retalhos miocutâneos da fáscia lata e outros. Relato de Caso: Neste relato é apresentada uma reconstrução da cobertura total do pênis por meio do uso de retalho miocutâneo do músculo cremaster com pele da bolsa escrotal, conseguindo prover uma boa vascularização e mantendo a permeabilidade uretral. Conclusão: Tal técnica não foi encontrada em nenhuma das bases de dados pesquisadas no trabalho, apenas semelhantes, e mostrouse como uma boa opção para a reconstrução total da cobertura cutânea peniana.

ABSTRACT Introduction: The penis is an important structure of the male body, and its reconstruction is a challenge. Several diseases and deformities affect this organ, being necessary, in certain cases, for the total reconstruction of the cutaneous coverage of the penis, having already been described in the literature several techniques, such as the use of total grafts, scrotal flap, myocutaneous flaps of the fasciae latae and others. Case Report: In this report, a reconstruction of the total coverage of the penis is presented using a myocutaneous flap of the cremaster muscle with skin from the scrotum, achieving good vascularization and maintaining urethral permeability. Conclusion: This technique was not found in any of the databases researched in this study, only similar ones, and it proved to be a good option for the total reconstruction of penile skin coverage.

RESUMO Introdução: A doença de Milroy manifesta-se como linfedema de membros inferiores e região genital, o que provoca prejuízos físicos e sociais. Relato de Caso: Reporta-se um caso de linfedema penoescrotal severo em um paciente com doença de Milroy. Foi realizada a ressecção cirúrgica do tecido afetado e a reconstrução com retalhos locais e enxerto de pele. Discussão: A doença de Milroy é rara, de caráter autossômico dominante. Sua apresentação clínica é progressiva e decorre da hipoplasia dos vasos linfáticos dos membros inferiores. O tratamento em casos avançados é iminentemente cirúrgico. Conclusão: No caso apresentado, o tratamento cirúrgico é uma boa opção. O uso de retalho paraescrotal para escrotoplastia associado ao enxerto para cobertura do pênis proporciona bom resultado funcional.

ABSTRACT Introduction: Milroy disease manifests itself as lymphedema of the lower limbs and genital region, which causes physical and social damage. Case Report: A case of severe-scrotal lymphedema in a patient with Milroy disease. Surgical resection of the affected tissue and reconstruction with local flaps and skin graft were performed. Discussion: Milroy disease is a rare autosomal dominant disease. The clinical presentation is progressive and results from hypoplasia of the lymphatic vessels of the lower limbs. Treatment in advanced cases is mainly surgical. Conclusion: In the case of a patient with Milroy disease and severe penoscrotal lymphedema, surgical treatment is a good option. The use of parascrotal flaps for scrotoplasty associated with a graft to recover the penis provides a good functional result.

Resumo A dor escrotal aguda é uma causa frequente de admissão no serviço de urgência. No entanto, a trombose do plexo pampiniforme é uma causa rara de dor escrotal. Os autores apresentam o caso de um homem de 44 anos que recorre ao serviço de urgência por dor escrotal esquerda com 5 dias de evolução, após queda da própria altura em posição sentado.

Abstract Acute scrotal pain is a frequent cause of admission in the emergency room. However, painful scrotum due to pampiniform plexus thrombosis is rare. The authors discuss a case of a 44-year-old man who presented to the emergency department with left scrotal pain with 5 days of duration, after falling from his own height in a sitting position.

RESUMEN Introducción. La trombosis de la vena espermática (TVE) es una entidad muy poco frecuente de la cual no se tienen datos epidemiológicos específicos. Su presentación es de predominio izquierdo, en la mayoría de los casos su causa es desconocida y su diagnóstico suele realizarse por exclusión en el estudio del escroto agudo. A continuación, se presenta el primer caso documentado de TVE en Colombia y uno de los pocos de lateralidad derecha en el mundo. Presentación del caso. Hombre de 21 años quien consultó al servicio de urgencias de una institución de tercer nivel de atención de Bogotá, Colombia, por un cuadro clínico de una semana de evolución consistente en dolor en región inguinoescrotal derecha que aumentó progresivamente de intensidad y estuvo acompañado de un pico febril no cuantificado; el paciente indicó como único antecedente médico un trauma craneoencefálico leve sin secuelas a los 20 años. Se realizó estudio con ecografía Doppler testicular en donde se observó trombosis del cordón espermático derecho. Se inició manejó con antibioticoterapia, heparinas de bajo peso molecular y cumarínicos, con lo cual se obtuvo una adecuada respuesta y la resolución del cuadro. Conclusión. La TVE representa un reto diagnóstico, por lo que se requiere de una alta sospecha clínica, la cual se genera teniendo conocimiento de la entidad e incluyéndola en el diagnóstico diferencial del escroto agudo. La ecografía Doppler es una herramienta fundamental para diagnosticar TVE, además permite iniciar un tratamiento conservador oportuno, seguro y eficaz que evite desenlaces desfavorables para el paciente, lo que resulta ser costo-efectivo.

ABSTRACT Introduction: Spermatic vein thrombosis (SVT) is a very rare event with no specific epidemiological data. Its presentation is predominantly on the left, and in most cases, its cause is unknown. Its diagnosis is usually made by exclusion when studying acute scrotum pain. The following is the first case of SVT reported in Colombia and one of the few cases of right laterality in the world. Case presentation. A 21-year-old male patient consulted the emergency department of a tertiary care institution in Bogotá, Colombia, due to pain in the right inguinoscrotal region for a week that progressively increased in intensity and was accompanied by unquantified fever, without other associated symptoms. The patient reported only a medical history of a mild cranioencephalic trauma without sequelae at the age of 20 years. A testicular Doppler ultrasound was performed, revealing right spermatic cord thrombosis. He started antibiotic therapy, low molecular weight heparins and coumarin, which resulted in an adequate response and resolution of the condition. Conclusion: SVT poses a diagnostic challenge that requires a high clinical suspicion, which is achieved by having knowledge of this condition and establishing it as a differential diagnosis of acute scrotum pain. Once suspected, Doppler ultrasound becomes a useful tool for diagnosis because, in addition to being cost-efficient, it allows the initiation of a timely, safe and effective conservative treatment, thus avoiding unfavorable outcomes for the patient.

ABSTRACT Fournier’s gangrene is a condition mainly found in adults and it very rarely occurs in children. Multiple predisposing factors have been identified for children, including circumcision, diaper dermatitis, the occurrence of abscesses, anorectal trauma, and immune deficiency. Characteristic signs and symptoms include rapidly progressing edema and hyperemia in the perineal region, accompanied by intense pain and fever. Once Fournier’s gangrene is diagnosed, therapy must be immediately instituted, using wide spectrum intravenous antibiotics and early surgical debridement of devitalized tissues. We present a case report including clinical and epidemiological characteristics of two pediatric patients with Fournier’s gangrene who received medical and surgical therapy at the Instituto Nacional de Salud del Niño in San Borja, Lima, Peru.

RESUMEN La gangrena de Fournier es una patología que se encuentra predominantemente en varones adultos y extremadamente rara en niños. Se han descrito múltiples factores predisponentes en los niños, incluyendo la circuncisión, la dermatitis del pañal, la presencia de abscesos, traumatismos anorrectales y deficiencias inmunológicas. Los signos y síntomas característicos incluyen edema e hiperemia de rápida evolución en la región perineal acompañados de dolor intenso y fiebre. Una vez que se diagnostica la gangrena de Fournier, se debe instaurar tratamiento de forma inmediata, antibióticos endovenosos de amplio espectro y debridamiento quirúrgico temprano del tejido desvitalizado. A continuación presentamos un reporte de casos que incluye las características clínicas y epidemiológicas de dos pacientes pediátricos con gangrena de Fournier que recibieron tratamiento médico y quirúrgico en el Instituto Nacional de Salud del Niño de San Borja.
