ABSTRACT Objective: To conduct a bibliographic review on tuberculosis (TB) disease in children and adolescents with rheumatic diseases, being managed with biologic therapy. Data source: An integrative review with a search in the U.S. National Library of Medicine and the National Institutes of Health (PubMed) using the following descriptors and Boolean operators: ([“tuberculosis”] AND ([“children”] OR [“adolescent”]) AND [“rheumatic diseases”] AND ([“tumor necrosis factor-alpha”] OR [“etanercept”] OR [“adalimumab”] OR [“infliximab”] OR [“biological drugs”] OR [“rituximab”] OR [“belimumab”] OR [“tocilizumab”] OR [“canakinumab”] OR [“golimumab”] OR [“secukinumab”] OR [“ustekinumab”] OR [“tofacitinib”] OR [“baricitinib”] OR [“anakinra”] OR [“rilonacept”] OR [“abatacept”]), between January 2010 and October 2021. Data synthesis: Thirty-seven articles were included, with the total number of 36,198 patients. There were 81 cases of latent tuberculosis infection (LTBI), 80 cases of pulmonary tuberculosis (PTB), and four of extrapulmonary tuberculosis (EPTB). The main rheumatic disease was juvenile idiopathic arthritis. Among LTBI cases, most were diagnosed at screening and none progressed to TB disease during follow-up. Of the TB cases using biologics, most used tumor necrosis factor-alpha inhibitors (anti-TNFα) drugs. There was only one death. Conclusions: The study revealed a low rate of active TB in pediatric patients using biologic therapy. Screening for LTBI before initiating biologics should be done in all patients, and treatment, in cases of positive screening, plays a critical role in preventing progression to TB disease.

RESUMO Objetivo: Fazer um levantamento bibliográfico referente à tuberculose (TB) em crianças e adolescentes com doenças reumáticas, em uso de imunobiológicos. Fonte de dados: Revisão integrativa com busca na base United States National Library of Medicine (PubMed) utilizando os descritores e operadores booleanos: ([“tuberculosis”] AND ([“children”] OR [“adolescent”]) AND [“rheumatic diseases”] AND ([“tumor necrosis fator-alpha”] OR [“etanercept”] OR [“adalimumab”] OR [“infliximab”] OR [“biological drugs”] OR [“rituximab”] OR [“belimumab”] OR [“tocilizumab”] OR [“canakinumab”] OR [“golimumab”] OR [“secukinumab”] OR [“ustekinumab”] OR [“tofacitinib”] OR [“baricitinib”] OR [“anakinra”] OR [“rilonacept”] OR [“abatacept”]), entre janeiro de 2010 e outubro de 2021. Síntese de dados: Trinta e sete artigos foram incluídos, com o total de 36.198 pacientes. Houve 81 casos de tuberculose latente (ILTB), 80 casos de tuberculose pulmonar (TBP) e quatro casos de tuberculose extrapulmonar (TBEP). A principal doença reumática foi a artrite idiopática juvenil. Entre os casos de ILTB, a maioria foi diagnosticada no rastreio e nenhum evoluiu para a TB. Dos casos de TB em uso de imunobiológicos, a maioria utilizava fármacos antiTNFα. Houve somente um caso de óbito. Conclusões: O estudo demonstrou baixa taxa de TB nos pacientes pediátricos em uso de imunobiológicos. O rastreio para ILTB antes do início da terapia com agentes biológicos deve ser realizado em todos os pacientes, e o tratamento, nos casos de rastreio positivo, é importante para evitar a progressão para TB doença.

Tuberculous mastoiditis (TBM) is a rare form of extrapulmonary tuberculosis (TB), which may result in catastrophic complications, including mastoid and ossicle destruction, hearing loss and intracranial spread if untreated. Diagnosis is challenging due to the paucibacillary nature of extrapulmonary TB, compounded by limited theatre access for specimen retrieval, resulting in delayed diagnosis and treatment initiation. In this case series, we discuss three cases of TBM (one paediatric and two adults) who presented to the public and private healthcare sectors in the Eastern Cape in 2022, underscoring that TB does not respect socioeconomic status.

Abstract Infants are a particularly vulnerable group for the development of severe and/or extrapulmonary forms of tuberculosis. The difficulty in establishing a definitive and timely diagnosis contributes to the high morbimortality in this age group. Investigation often relies on a high index of suspicion. Herein is reported a case of disseminated tuberculosis in an infant that highlights its clinical complexity and diagnostic challenge.

Resumo Os lactentes representam um grupo particularmente vulnerável para o desenvolvimento de formas severas e/ou extrapulmonares de tuberculose. A dificuldade em estabelecer um diagnóstico definitivo e atempado contribui para a elevada morbimortalidade nesta faixa etária. Particularmente nestes doentes, a investigação depende frequentemente de um elevado índice de suspeição. É reportado um caso de tuberculose disseminada num pequeno lactente que evidencia a sua complexidade clínica e desafio diagnóstico.

Resumen Tenosinovitis es la inflamación o infección de un tendón y su vaina sinovial. Una de las causas puede ser bacteriana. Los gérmenes comunes son los más frecuentes, pero deben investigarse también las micobacterias. En la Argentina, la tuberculosis es un problema de salud pública. Mycobacterium bovis ocasiona zoonosis que afectan animales y humanos. La infección en el hombre se da por inhalación de aerosoles de ganado enfermo, por vía digestiva o cutánea. Las manifestaciones extrapulmonares pueden ser digestivas, ganglionares, cutáneas u osteoarticulares. La tenosinovitis tuberculosa de muñeca es infrecuente y, generalmente, es diagnosticada como tenosinovitis reumática o inespecífica. Se presenta el caso de una mujer de 48 años, residente de zona rural, que presentaba hipertrofia y edema en dedos de la mano izquierda. Se le realizó cirugía del túnel carpiano y se observaron cuerpos como granos de arroz. Del tejido sinovial se aisló M. bovis. Comenzó tratamiento tuberculostático más claritromicina. Evolucionó favorablemente.

A causa pode ser bacteriana, sendo os germes comuns os mais frequentes, mas as micobactérias devem ser investigadas. Na Argentina, a tuberculose é um problema de saúde pública. Mycobacterium bovis causa zoonose que afeta animais e humanos. A infecção no homem ocorre por inalação de aerossóis de gado doente, por via digestiva ou cutânea. As manifestações extrapulmonares podem ser digestivas, ganglionares, cutâneas, osteoarticulares. A tenossinovite tuberculosa do pulso é pouco frequente, geralmente diagnosticada como tenossinovite reumática ou inespecífica. Apresenta-se o caso de uma mulher de 48 anos, moradora de zona rural, com hipertrofia e edema nos dedos da mão esquerda. Foi realizada cirurgia do túnel do carpo, observando-se corpos como grãos de arroz. Do tecido sinovial foi isolado M. bovis. Iniciou-se tratamento tuberculostático mais claritromicina. Evoluiu favoravelmente.

Abstract Tenosynovitis is an inflammation or infection of a tendon and its synovial sheath. One cause of this illness may be bacterial, being common organisms more frequent, but mycobacteria should be also investigated. In Argentina, tuberculosis is a public health problem. Mycobacterium bovis causes zoonoses that affect animals and humans. Infection in man occurs by inhalation of aerosols from sick cattle, by digestive or cutaneous routes. Extrapulmonary manifestations can be digestive, nodal, cutaneous or osteoarticular. Tuberculous wrist tenosynovitis is uncommon, usually diagnosed as rheumatic or nonspecific tenosynovitis. The case of a 48-year-old woman, a resident of rural areas, presenting hypertrophy, and edema in the fingers of the left hand was introduced. Carpal tunnel surgery was performed, while rice grain bodies were noticed. Synovial tissue material was taken for mycobacterial culture, where M. bovis was isolated. She began tuberculostatic treatment plus clarithromycin. She evolved favourably.

Resumen Introducción: El objetivo de este estudio fue describir las características clínicas y demográficas de niños con enfermedad tuberculosa confirmada e identificar los factores asociados. Métodos: Se realizó un estudio observacional retrolectivo en el Hospital Civil de Guadalajara Dr. Juan I. Menchaca. Se incluyeron menores de 18 años hospitalizados y ambulatorios que se notificaron al Sistema Nacional de Vigilancia Epidemiológica (SINAVE) por sospecha de tuberculosis y que contaron con pruebas moleculares o microbiológicas para micobacterias. El estudio de los factores asociados se realizó mediante análisis multivariado con regresión logística. Resultados: Se incluyeron en el estudio 109 menores de 18 años con sospecha de tuberculosis. El 50.5% (55/109) fueron de sexo masculino y la mediana de edad fue de 11 años. Se confirmó enfermedad tuberculosa en el 55% (n = 60) de los casos: el 15% (9/60) presentaron infección pulmonar y el resto extrapulmonar. Las pruebas diagnósticas utilizadas fueron el estudio histopatológico (n = 26), tinciones de expectoración o aspirado gástrico (n = 17), reacción en cadena de la polimerasa (n = 12) y cultivos (n= 5). 33.9% de los pacientes presentaron prueba de derivado proteico purificado (PPD) o ensayo de liberación de interferón gamma (IGRA) positiva. Se observó que la desnutrición (razón de momios (RM) 15.9, intervalo de confianza (IC) 95% 2.3 - 109) y el consumo de productos no pasteurizados (RM 7.45, IC 95% 1.02 - 54.3) se asociaron con enfermedad tuberculosa en niños. Conclusiones: La desnutrición y el consumo de lácteos no pasteurizados se asocian con la enfermedad tuberculosa.

Abstract Background: This study aimed to describe the clinical and demographic characteristics of children with confirmed tuberculosis disease and identify associated factors. Methods: We conducted a retrospective and observational study at the Hospital Civil de Guadalajara Dr. Juan I. Menchaca. Inpatient and outpatient children under 18 years of age who were reported to the National Epidemiological Surveillance System (SINAVE, for its Spanish acronym) for suspected tuberculosis and who had molecular or microbiological tests for mycobacteria were included in the study. Multivariate analysis with logistic regression was used to analyze associated factors. Results: One hundred and nine patients under 18 years of age with suspected tuberculosis were included in the study. About 50.5% (55/109) were male, and the median age was 11 years. Tuberculosis was confirmed in 55% (n = 60): 15% (9/60) had a pulmonary infection, and the rest (51/60) had an extrapulmonary infection. The diagnostic tests used were histopathological study (n = 26), expectoration or gastric aspirate stains (n = 17), polymerase chain reaction (n = 12), and cultures (n = 5). Positive purified protein derivative (PPD) or interferon-gamma release assay (IGRA) tests were found in 33.9%. Malnutrition (odds ratio [OR] 15.9, 95% confidence interval [CI]: 2.3-109), and consumption of unpasteurized products (OR 7.45, 95% CI: 1.02-54.3) were associated with tuberculosis disease in children. Conclusions: Malnutrition and consumption of unpasteurized dairy products are associated with tuberculosis.

RESUMEN El compromiso ocular es una forma extrapulmonar de tuberculosis. Puede comprometer cualquier componente del sistema visual. Las manifestaciones oculares pueden ser causadas por una infección activa que invade el ojo o por una reacción inmunológica de hipersensibilidad retardada. Las presentaciones clínicas más comunes son uveítis anterior crónica, coroiditis y esclero-queratitis. A pesar de la existencia de herramientas moleculares altamente sensibles, arribar al diagnóstico de formas poco frecuentes o no pensadas como la TB ocular en un niño sigue siendo un gran reto y se basa en la presentación clínica, evaluación sistémica y la respuesta terapéutica. El tratamiento implica el uso de antifímicos y, muchas veces, esteroides. El objetivo fue presentar una forma de tuberculosis endoftálmica, pulmonar miliar y meníngea, en el marco de la drogorresistencia.

SUMMARY Eye engagement is an extrapulmonary form of tuberculosis. It can compromise any component of the visual system. Eye manifestations can be caused by an active infection that invades the eye or by a delayed hypersensitivity immune reaction. The most com mon clinical presentations are: chronic anterior uveitis, choroiditis and sclero-keratitis. Despite the existence of highly sensitive molecular tools, arriving at diagnosis in rare or undeceived ways with eye tuberculosis in a child remains a major challenge, based on clinical presentation, systemic evaluation and therapeutic response. Treatment involves the use of antiphymics and often steroids. The objective was to present a form of endophthalmic tuberculosis, miliary pulmonary and meningeal, in the framework of drug resistance.

ABSTRACT Ocular involvement is an extrapulmonary manifestation of tuberculosis (TB). It can affect any element of the visual system. Ocular manifestations may be caused by an active infection that invades the eye or by an immunological reaction of retarded hypersensi tivity. The most common clinical presentations are: chronic anterior uveitis, choroiditis, and sclero-keratitis. Despite the existence of highly-sensitive molecular tools, making a diagnosis of uncommon or unknown forms of the disease, such as ocular TB (OTB) in children is still a major challenge, based on clinical presentation, systemic evalua tion, and therapeutic response. The treatment includes the use of antiphymics and, on many occasions, steroids. The objective was to present a form of endophthalmic, pulmonary, miliary, and meningeal tuberculosis, within the framework of drug-resistance.

Resumen En 2020 se enfermaron de tuberculosis 9.9 millones de personas, estimándose 1.5 millones de muertes. El 9% de los casos de tuberculosis extrapulmonar cursan con afección genital, y presentan Ca-125 elevado, masa pelviana y ascitis, lo que sugiere neoplasias y enmascara infecciones granulomatosas. Se describe el caso de una paciente con absceso tubo-ovárico tuberculoso.

Abstract In 2020, 9.9 million people became ill with tuberculosis, with an estimated 1.5 million deaths. 9% of extrapulmonary tuberculosis courses with genital involvement, presenting elevated Ca-125, pelvic mass and ascites suggesting neoplasms, masking granulomatous infections. The case of a patient with a tuberculosis tubo-ovarian abscess is described.

Resumen La tuberculosis extrapulmonar es aquella tuberculosis diagnosticada clínicamente y confirmada por estudios bacteriológicos que afecta a tejidos y órganos fuera del parénquima pulmonar. México es el tercer lugar en América Latina en incidencia de tuberculosis pulmonar y extrapulmonar. Los métodos de cultivo siguen siendo el método de referencia para el diagnóstico de tuberculosis extrapulmonar, ya que identifican la especie y la sensibilidad a los fármacos.

Abstract Extrapulmonary tuberculosis is defined as that case of tuberculosis clinically diagnosed and confirmed by bacteriological studies that affects tissues and organs outside the lung parenchyma. Mexico is in third place among Latin American countries in terms of the incidence of pulmonary and extrapulmonary tuberculosis. Culture methods are still the gold standard for the diagnosis of extrapulmonary tuberculosis since they identify the species and susceptibility to drugs.

Resumo: O Brasil é um dos 30 países com maior incidência de tuberculose (TB). Pessoas em situação de rua (PSR) têm 56 vezes mais riscos para o adoecimento do que a população geral por terem menor renda e acesso à saúde. Os objetivos do estudo foram apresentar o perfil sociodemográfico e epidemiológico de PSR notificadas para TB entre 2015 e 2019 na cidade do Rio de Janeiro e analisar relações entre as variáveis estudadas e desfechos da TB. Trata-se de estudo transversal com dados secundários das notificações de TB em PSR no período e local do estudo. Foi realizada análise descritiva, seguida da verificação de associação entre variáveis selecionadas e desfechos para TB, com teste qui-quadrado e regressão logística multinomial, para obtenção da razão de chances (OR). O perfil predominante das PSR com TB é de homens (74,9%), negros (76,2%), com idade média de 43,3 anos (DP = 12,0) e faixa etária entre 30 e 59 anos (78,5%). O desfecho mais frequente foi abandono do tratamento (43,3%), seguido por cura (29,9%) e óbito (3,6%). As análises mostraram que raça negra (OR = 1,4; IC95%: 1,1-1,9) e uso de drogas (OR = 1,7; IC95%: 1,3-2,3) e álcool (OR = 1,3; IC95%: 1,0-1,7) foram fatores de risco para abandono do tratamento, enquanto faixas etárias a partir de 30 anos (OR = 0,7; IC95%: 0,5-0,9) e forma extrapulmonar (OR = 0,2; IC95%: 0,1-0,6) foram aspectos de proteção. A vulnerabilidade das PSR se particulariza em perfis de raça e gênero, tal qual a TB, portanto, é necessário reforçar ações de prevenção e tratamento efetivas para aumentar o acesso aos serviços de saúde e o enfrentamento da TB nesse contexto, além de atentar para a alta proporção de dados incompletos que limitam as análises desse agravo.

Resumen: Brasil es uno de los treinta países con mayor incidencia de tuberculosis (TB), y las personas en situación de calle (PSC) tienen 56 veces más riesgo de contraer la enfermedad que la población en general debido a menores ingresos y acceso a la salud. El objetivo de este estudio fue presentar el perfil sociodemográfico y epidemiológico de las PSC diagnosticas con TB entre 2015 y 2019 en la ciudad de Río de Janeiro, así como analizar las relaciones entre las variables estudiadas y los resultados de la TB. Se trata de un estudio transversal, con datos secundarios de los casos de TB en las PSC para el período y el lugar del estudio. Se realizó el análisis descriptivo, seguido del análisis de la asociación entre las variables seleccionadas y los resultados para TB con la aplicación de la prueba de chi-cuadrado y de regresión logística multinomial para obtener el odds ratio (OR). En el perfil de las PSC con TB se encuentran hombres (74,9%) negros (76,2%), de edad promedio de 43,3 años (DE = 12,0), en el grupo de edad de entre 30 y 59 años (78,5%). El resultado más frecuente fue el abandono del tratamiento (43,3%), seguido de la cura (29,9%) y la muerte (3,6%). Los análisis mostraron que la raza negra (OR = 1,4; IC95%: 1,1-1,9), el consumo de drogas (OR = 1,7; IC95%: 1,3-2,3) y el alcohol (OR = 1,3; IC95%: 1,0-1,7) fueron los factores de riesgo para el abandono del tratamiento, y que los grupos de edad de más de 30 años (OR = 0,7; IC95%: 0,5-0,9) y la forma extrapulmonar (OR = 0,2; IC95%: 0,1-0,6) fueron los factores protectores. La vulnerabilidad de las PSC se agudiza en los perfiles de raza y de género tal como la TB, por lo que es necesario fortalecer las acciones efectivas de prevención y tratamiento para aumentarles el acceso a los servicios de salud y el combate de la TB en este contexto. Y, además, prestar atención a la alta proporción de datos incompletos que limitan los análisis para esta condición.

Abstract: Brazil is one of the 30 countries with the highest incidence of tuberculosis (TB) and homeless people (HP) have 56 times more risk for illness than the general population, due to lower income and access to health. This study aimed to present the sociodemographic and epidemiological profile of HP notified for TB from 2015 to 2019 in the municipality of Rio de Janeiro and to analyze relationships between the variables studied and TB outcomes. This is a cross-sectional study with secondary data on TB notifications in HP in the period and place of the study. Descriptive analysis was performed, followed by analysis of the association between selected variables and TB outcomes with chi-square test and multinomial logistic regression to obtain the odds ratio (OR). The profile of HP with TB is men (74.9%), blacks (76.2%), with a mean age of 43.3 years (SD = 12.0), aged from 30 to 59 years (78.5%). The most frequent outcome was treatment withdrawal (43.3%), followed by cure (29.9%), and death (3.6%). The analyses showed that black individuals (OR = 1.4; 95%CI: 1.1-1.9), drug (OR = 1.7; 95%CI: 1.3-2.3) and alcohol use (OR = 1.3; 95%CI: 1.0-1.7) were risk factors for treatment withdrawal and that age groups older than 30 years or older (OR = 0.7; 95%CI: 0.5-0.9) and the extrapulmonary form (OR = 0.2; 95%CI: 0.1-0.6) were protective factors. The vulnerability of the HP is particularized in racial and gender profiles, as well as TB, thus reinforcing effective prevention and treatment actions is necessary to increase access to health services and the fight against TB in this context. And pay attention to the high proportion of incomplete data that limit the analyses for this problem.

BACKGROUND: HIV and AIDS continues to impose substantial healthcare challenges in sub-Saharan Africa, but there are limited local data comparing inpatient outcomes between people with HIV (PLWH) and those uninfected OBJECTIVES: To compare cause-specific mortality among hospitalised adolescents and adults, stratified by HIV-serostatus METHOD: A cross-sectional analysis was performed, analysing cause-specific inpatient mortality data and total admissions, from 01 January 2017 to 30 June 2020, at Tshepong Hospital, North West province, South Africa RESULTS: The overall inpatient mortality rate decreased from 14.5% (95% confidence interval [CI]: 13.4-16.0) in 2017, to 11.3% (95% CI: 10.6-11.9) in 2020; P < 0.001. People living with HIV accounted for 53.9% (n = 2342) of inpatient deaths, 22.6% (n = 984) were HIV-seronegative patients and 23.5% (n = 1020) patients with unknown HIV-serostatus. People with HIV died at younger ages (median: 44 years, interquartile range [IQR]: 35.8-54.2) compared to HIV-seronegative inpatients (median: 64.4 years, IQR: 55.5-73.9); P < 0.001. Leading causes of death were pneumonia (19.9%, n = 863), then pulmonary and extrapulmonary tuberculosis (15.0%, n = 654). People with HIV who had CD4+ counts < 350 cells/mL or viral load ≥ 1000 copies/mL had increased risk of death from tuberculosis compared to virally suppressed patients (adjusted relative risk: 2.10 [95% CI: 1.44-3.04, P < 0.009] and 1.56 [95% CI: 1.22-2.00, P < 0.001 CONCLUSION: Our study, conducted in a regional hospital in South Africa, showed PLWH had higher mortality rates and died at younger ages compared to HIV-seronegative patients

In this clinical case, a man presented with a groin injury on his dominant side, which he apparently sustained in football (soccer) practice on the previous day. The man was unable to walk unassisted and had to be transported in a wheelchair. The consulting practitioner grew suspicious upon finding minimal clinical evidence and nothing notable on the X-ray to suggest a severe acute injury. A subsequent detailed workup revealed extrapulmonary tuberculosis (EPTB) of the musculoskeletal (MSK) and genitourinary tract (GUT) systems, complicated by a pathological fracture of the acetabulum, as the cause of the groin injury. Management of the EPTB resolved the condition with no relapse nor long-term sequelae beyond five years, despite being immunocompromised. We present the clinical case and a five year follow-up. The case serves as a reminder of the possibility that other conditions may mimic sports injuries and further illustrates a rare presentation of such a condition.

ABSTRACT Pericardial tuberculosis (TBP) is a rare manifestation of extrapulmonary tuberculosis (TB). It presents insidiously and nonspecifically, making diagnosis difficult and delaying treatment, leading to serious complications such as pericardial effusion with signs of cardiac tamponade or constrictive pericarditis. The case of an 18-year-old female patient, pregnant, with a history of close contact with a relative with pulmonary TB is described; she consulted the Emergency Service for dyspnea. Among the studies requested, the echocardiogram showed pericardial effusion with compression of cavities, requiring pericardiocentesis. Pericardial fluid culture revealed Mycobacterium tuberculosis and antituberculous treatment plus corticosteroids were started. It evolved with a recurrence of effusion despite adequate medical treatment and the performance of a pericardial window.

RESUMEN La tuberculosis pericárdica es una manifestación poco frecuente de la tuberculosis extrapulmonar. Se presenta de manera insidiosa e inespecífica, lo que dificulta el diagnóstico, retrasa el tratamiento, y lleva a complicaciones graves, como el derrame pericárdico con signos de taponamiento cardíaco o pericarditis constrictiva. Se describe el caso de una paciente femenina de 18 años, embarazada, con antecedente de contacto estrecho con familiar con tuberculosis pulmonar, que consultó al servicio de urgencias por disnea. Entre los estudios solicitados, el ecocardiograma evidenció la presencia de un derrame pericárdico con compresión de cavidades, por lo que requirió pericardiocentesis. El cultivo del líquido pericárdico informó Mycobacterium tuberculosis y se inició tratamiento antituberculosis y corticoides. Evolucionó con recurrencia del derrame a pesar de tratamiento médico adecuado y realización de ventana pericárdica.

Abstract Rationale Perianal tuberculosis is extremely rare without previous or active pulmonary infection. Ulcerative skin lesion is a rare presentation of extrapulmonary tuberculosis in the oral, perianal, or genital mucosa and the adjacent skin. Case report A 71-year-old woman complained of pain during evacuation and fecal incontinence for two years. There was an ulcerated lesion in the perianal and intergluteal region and perianal fistulous tracts. A polymerase chain reaction test on blood and biopsies of perianal ulcers, perianal fistula, and the intergluteal area was positive for Mycobacterium tuberculosis. The pathological examination revealed a chronic epithelioid granulomatous inflammatory process with the presence of multinucleated giant cells. After the end of the tuberculosis drug regimen, there was marked improvement in the patient's clinical condition. Conclusion Even in the absence of an identifiable primary focus, tuberculosis should be considered in the differential diagnosis of ulcerative and fistulous lesions of the perianal area.
