Abstract Background: Anogenital warts are the leading sexually transmitted infection in patients seeking care at specialized clinics. They may display a vast array of forms, according to the interaction of the virus with the host's immunity. Cellular immunity is the epithelium's main form of defense against the virus, involving an active participation of the Langerhans cells and pro-inflammatory cytokines such as TNF-α. Objective: To assess the epithelial immune response of anogenital warts in males, according to the number of lesions presented. Methods: This is a prospective, cross-sectional study carried out at the dermatology outpatient clinic in a tertiary hospital. We included male patients over 18 years of age without comorbidities who had anogenital condylomata and no previous treatments.In order to evaluate the local epithelial immunity, the lesions were quantified, then removed and employed in CD1a immunohistochemistry assays for assessing the morphometry and morphology of Langerhans cells; TNF-α; reaction was used for determining cytokine positivity in the epithelium. Results: 48 patients were included in the study. There was no statistically significant difference as to the number of Langerhans cells, in their morphology, or the presence of TNF-α. However, patients presenting with more Langerhans cells in the lesions had cells with a star-like and dendritic morphology, whereas in those with a lower cell count had cells with a rounded morphology and no dendrites (p < 0.001). Study limitations: Small number of patients analyzed. Conclusion: There was no difference in epithelial immunity between patients having few or many anogenital condyloma lesions as measured by the morphology and morphometry of Langerhans cells and TNF-α; positivity. Such an assessment employing immunity markers differing from the usual ones is expected to yield useful results.

Abstract Cancer of the vulva accounts for at least 1% of malignant neoplasms among women. Although rare, vulvar melanoma is the second most common histological type of vulvar cancer, representing 7-10% of all malignant vulvar neoplasms. Initial symptoms are non-specific and complete excision of the lesion is indicated in cases with suspected diagnosis. Prognosis of patients with these neoplasms is poor and remains unchanged despite the treatment approach. Hemivulvectomy with lymph node dissection is the current procedure of choice, associated or not with adjuvant therapies. We report two cases of patients presenting with late diagnosed vulvar melanoma and the relevant aspects in their therapeutic management.

Abstract: Vulvar cancer accounts for less than 1% of malignancies in women. Verrucous carcinoma of the vulva is a rare histological variation, comprising less than 1% of vulvar cancer cases. Although it is characterized as being locally invasive, the condition is not associated with metastatic spreading. Lesions present in the form of a verrucous, ulcerated, and bleeding tumor that can reach large dimensions. This type of tumor can be mistaken for condylomata, both macroscopically and microscopically. We report the case of an 81-year-old patient with a large vulvar tumor presented for eight years, initially considered as a Buschke-Löwenstein tumor. The patient underwent radical vulvectomy with a V-Y advancement flap technique. This type of tumor should be considered by clinicians dealing with condylomatous ulcerative lesions that do not respond to the usual treatment.

Abstract: Porokeratosis is a disorder of epidermal keratinization characterized clinically by a distinctive ridge-like border, and histologically by cornoid lamellae. The known clinical variants of porokeratosis are: classic porokeratosis of Mibelli, disseminated superficial (actinic) porokeratosis (DSAP), porokeratosis palmaris et plantaris disseminata, linear porokeratosis and punctate porokeratosis. In 1995, a seventh form was described as porokeratosis ptychotropica: a verrucous form resembling psoriasis involving the gluteal cleft presenting on the histological exam multiple cornoid lamellae. There are very few reports in the literature of this clinical variant. The present study describes the case of a healthy male presenting gluteal hyperkeratotic plaques for 22 years. He had been to several dermatologists, none of them had achieved a definitive diagnosis. We present a typical clinical presentation and its dermoscopy findings, in addition to histological examination that confirmed the diagnosis.

O Dermatofibrosarcoma protuberans (DFSP) é uma neoplasia maligna rara em ginecologia com probabilidade de recidiva local e baixo risco para metástases. Paciente com 34 anos com endometriose tratada apresentou dores na região inguinal esquerda. Reportava sensação de aumento gradual em nódulo palpável indolor e de difícil mobilização. Exérese da lesão foi realizada com hipótese diagnóstica de endometriose. A microscopia revelou neoplasia mesenquimal com proliferação de células fusiformes monomórficas e aspecto estoriforme caracterizando o DFSP. DFSP deve ser lembrado no diagnóstico diferencial das afecções da região inguinal em ginecologia, pois, apesar de ser raramente encontrado, representa uma neoplasia maligna.

Dermatofibrosarcoma protuberans (DFSP) is a rare malignant neoplasia in gynecology, with probability of recurrence and low possibilities of metastasis. A 34-year-old patient after endometriosis treatment presented pain in the left inguinal region. She reported sensation of gradual increase in a solid nodule, painless at palpation, with difficult mobilization. Exeresis was proceeded with diagnostic hypothesis of endometriosis. Microscopy revealed a mesenchymal neoplasia characterized by proliferation of monomorphic fusiform cells and storiform aspect characterizing the DFSP.DFSP must be remembered in the differential diagnosis of the affections of the inguinal region in gynecology because it represents a malignant neoplasia, although it's rare.

Células glandulares atípicas (AGC) em esfregaços cervicovaginais são achados citológicos raros, porém de significado representativo. Sua incidência varia, na literatura, de 0,08% a 0,81%. O sistema Bethesda de 2001 classifica estas lesões glandulares como AGCs sem outras especificações, AGCs provavelmente neoplásicas, adenocarcinoma cervical in situ (AIS) e adenocarcinoma invasivo. Das mulheres portadoras de AGC, grande parte não apresentará qualquer tipo de alteração histológica em avaliação subseqüente. Entretanto, em 17,4% a 62,2% dos casos serão encontradas lesões histológicas significativas, como neoplasias intra-epiteliais cervicais, AIS, neoplasias escamosas e glandulares, cervicais e endometriais, bem como neoplasias de outras localizações. O risco de doença significativa está relacionado à subdivisão de AGC encontrada. Em virtude da elevada probabilidade de anormalidades histológicas significativas em casos de AGC, a simples repetição citológica é insuficiente para o seguimento dessa condição. Esta atualização descreve a epidemiologia, a avaliação e a conduta das pacientes portadoras dessa anormalidade citológica.

Atypical glandular cells (AGC) on cervical smears are unusual but important cytologic diagnosis. The incidence of AGC ranges from 0.08% to 0.81 % of all cervical smears tests. The 2001 Bethesda System nomenclature classifies these glandular lesions as AGC not otherwise specified, AGC favor neoplasia, endocervical adenocarcinoma in situ (AIS) and invasive adenocarcinoma. Of women with AGC smears, a great number will have no histologic abnormalities on further evaluation. However, 17.4% to 62.2% are found to have significant histologic lesions such as cervical intraepithelial neoplasia, AIS, squamous and glandular cancers from sites farther the cervix and endometrium. The risk of significant disease is related to the AGC subclassification that was found. Because of the high likelihood that AGC is associated with significant histological disease, simply repeating the cytological smear is not sufficient for the management of this condition. This review describes the epidemiology, evaluation and management of patients with these citologic readings.

OBJETIVOS: caracterizar histologicamente pólipos endometriais em mulheres após a menopausa e avaliar o risco de lesões hiperplásicas e neoplásicas neles contidos. MÉTODOS: análise retrospectiva de 82 casos de mulheres portadoras de histopatologia confirmatória de pólipo endometrial, submetidas à polipectomia histeroscópica devido ao diagnóstico de espessamento endometrial à ultra-sonografia transvaginal. Todos os prontuários pertinentes foram revisados para obtenção da história clínica, antecedentes, dados referentes ao exame histeroscópico e resultado final da histopatologia. RESULTADOS: das 82 mulheres avaliadas, 10,9% faziam uso de algum tipo de terapia hormonal e 28 (34,1%) queixavam-se de sangramento por via vaginal. Pólipo solitário foi encontrado em 56 mulheres (68,3%), em 19 casos (23,2%) foram encontrados dois pólipos e em 7 casos (3,6%), três ou mais pólipos. A avaliação histológica definitiva evidenciou pólipo benigno em 63 mulheres (76,8%), pólipos com hiperplasia em 17 casos (20,8%), sendo dez com hiperplasia simples sem atipias (12,2%) e sete com hiperplasia complexa sem atipias (8,6%). Em dois pólipos foi encontrada neoplasia associada (2,4%). Para a análise estatística foi empregado o teste do chi2, corrigido por Yates. Correlacionou-se a histologia dos pólipos com a presença ou não de sangramento genital (p=0,0056), o número de pólipos encontrados por mulher (p=0,921), e o tempo decorrido após a menopausa (p=0,720). CONCLUSÕES: pólipos endometriais são entidades freqüentemente encontradas após a menopausa, associando-se com baixa freqüência a hiperplasias e carcinomas endometriais e apenas o estudo histológico de todo espécime nos permite afastar malignidade.

PURPOSE: to characterize postmenopausal endometrial polyps and to determine risk for concomitant premalignant and malignant pathology. METHODS: a retrospective study including 82 postmenopausal women with a histological diagnosis of endometrial polyps who underwent hysteroscopic polypectomy, after a diagnosis of endometrial thickening made by transvaginal ultrasound, was performed. Medical reports provided clinical and gynecological history, data related to the operative hysteroscopy and definitive histological findings. RESULTS: among the 82 patients who underwent hysteroscopic polypectomy, 10.9% were receiving some type of hormonal therapy. Twenty-eight women (34.1%) reported abnormal vaginal bleeding. Single polyp was encountered in 56 women (68.3%), two polyps were found in 19 cases (23.2%) and in 7 cases (3.6%), three or more polyps were found. The definitive histopathologic analysis revealed 63 (76.8%) benign polyps, 17 (20.8%) hyperplastic polyps (10 cases 12.2% - of simple endometrial hyperplasia without cytologic atypia and 7 cases 8.6% - of complex endometrial hyperplasia without cytologic atypia). Two polyps (2.4%) were diagnosed as harboring neoplasia. For the statistical analysis we employed chi2 test improved by Yates. The authors correlated the polyps' histology with the occurrence of abnormal vaginal bleeding (p=0.0056), number of endometrial polyps (p=0.921) and time after menopause (p=0.720). CONCLUSIONS: endometrial polyps are commonly found entities in postmenopausal women, related with low frequency to endometrial hyperplasia or carcinomas and only histological evaluation seems to allow the exclusion of premalignant and malignant pathology.

OBJETIVO: correlacionar espessamento endometrial diagnosticado por ultra-sonografia com os achados histeroscópicos, em mulheres na pós-menopausa. MÉTODOS: foi realizado estudo transversal com avaliação histeroscópica em 121 mulheres na pós-menopausa, com diagnóstico de espessamento do endométrio por ultra-sonografia transvaginal. Das pacientes incluídas, 23 (19%) recebiam diferentes esquemas de hormonioterapia e 98 não referiam uso de reposição hormnonal.; 55 pacientes queixavam-se de sangramento por via vaginal e as restantes apresentavam-se sem esta condição. Os exames endoscópicos foram realizados ambulatorialmente, utilizando-se histeroscópio rígido de 4 mm. Para a distensão da cavidade uterina empregou-se gás carbônico (CO2). Biópsia foi praticada em todas as pacientes, com auxílio de cureta tipo Novak, de 3 mm, e o material obtido submetido a estudo histopatológico. RESULTADOS: a espessura do endométrio variou entre 6 e 38 mm, com média de 10,7 ± 5,3 mm. Os achados histeroscópicos foram: lesão polipóide, em 51 pacientes (42,1%); endométrio atrófico, em 15 (12,4%); sinéquia senil, em 15 (12,4%); espessamento focal, em 13 (10,7%); lesão cerebróide, em 6 (5,0%); endométrio proliferativo, em 5 (4,1%); muco, em 5 (4,1%); mioma, em 4 (3,3%); endométrio secretor, em 3 (2,5%); hiperplasia endometrial, em 3 (2,5%) e atrofia cística, em 1 (0,8%). Observou-se correlação entre os achados histeroscópicos e os resultados da histopatologia em 30 dos 51 casos de pólipo, em 12 dos 15 de endométrio atrófico e na totalidade dos casos sugestivos de hiperplasia endometrial e de adenocarcinoma. CONCLUSÃO: na maioria das pacientes, o exame histeroscópico revelou que não se tratava de real espessamento endometrial, mas sim de outras variedades de lesão da cavidade uterina.

PURPOSE: to correlate endometrial thickening diagnosed by ultrasonography with hysteroscopic findings in postmenopausal women. METHODS: a transversal study with hysteroscopic evaluation was performed in 121 postmenopausal women, with endometrial thickening diagnosed through transvaginal ultrasonography. In 98 women there was no history of hormonal replacement therapy, while the remaining 23 received different types of hormone; 55 patients complained of vaginal bleeding and the remaining did not present this condition. The endoscopic examinations were performed in the outpatient clinic, using a 4 mm rigid hysteroscope. For uterine cavity distention carbon dioxide (CO2) was used. Biopsy was performed in all patients, with a 3 mm Novak type curette, and the collected material was submitted to a histopathological study. RESULTS: endometrial thickening varied from 6 to 38 mm, with a mean of 10.7 ± 5.3 mm. The hysteroscopic findings were: polypoid lesion in 51 patients (42.1%); atrophic endometrium in 15 patients (12.4%); senile synechia in 15 patients (12.4%), focal thickening in 13 patients (10.7%); cerebroid lesion in 6 patients (5.0%); proliferative endometrium in 5 patients (4.1%); mucus in 5 patients (4.1%); myoma in 4 patients (3.3%); secreting endometrium in 3 patients (2.5%); endometrial hyperplasia in 3 patients (2.5%); and cystic atrophy in 1 patient (0.8%). Correlation between hysteroscopic findings and cytopathology was observed in 30 of 51 cases of polypoid lesion, in 12 of 15 cases of atrophic endometrium and in all cases in which the diagnosis of endometrial hyperplasia or adenocarcinoma was suspected. CONCLUSION: in the majority of the patients, the hysteroscopic examinations revealed that there was no genuine endometrial thickening but rather other types of lesion in the uterine cavity.
