RESUMO
Resumen: ANTECEDENTES: El carcinoma intraepitelial tubárico seroso es una lesión precursora del carcinoma invasivo de las trompas de Falopio que con frecuencia se diagnostica en el contexto de una salpingooforectomía bilateral profiláctica por patología ginecológica benigna. CASO CLÍNICO: Paciente nulípara, de 51 años, con cuadro clínico de dolor abdominal y elevación de marcadores tumorales CA-125 y CA-19.9, diagnosticada con útero polimiomatoso y sospecha de endometrioma en el ovario derecho. Después de la histerectomía subtotal con anexectomía bilateral, el estudio histológico de la pieza tubárica extirpada reportó focos microscópicos de carcinoma intraepitelial tubárico seroso, sin signos de invasión estromal. Por los hallazgos se solicitaron pruebas de imagen mamarias y el estudio genético de mutación BRCA 1 y 2. CONCLUSIÓN: La salpingooforectomía bilateral profiláctica es un procedimiento que reduce el riesgo de carcinomas peritoneales, tubáricos y serosos de ovario. Las pacientes con carcinoma intraepitelial tubárico seroso deben tener seguimiento basado en controles ecográficos, pruebas de imagen mamarias, determinación de marcadores tumorales y estudios genéticos, debido a su asociación con mutaciones en los genes BRCA 1 y 2.
Abstract: BACKGROUND: Serous tubal intraepithelial carcinoma (STIC) is a precursor lesion of invasive high-grade tubal and serous carcinoma of the ovary, frequently diagnosed in the context of prophylactic bilateral salpingoophorectomy for benign gynecological pathology. The objective of this work is to carry out a literature review on the most relevant aspects of the follow-up of this injury, after its incidental diagnosis in gynecological surgery. CLINICAL CASE: A 51-year-old nulliparous patient who, in the context of a clinical situation of abdominal pain with elevation of tumor markers CA125 and CA19.9, was diagnosed with polymomatous uterus and suspected endometrioma in the right ovary. After a subtotal hysterectomy with bilateral adnexectomy, the histological study of the excised tubal specimen found microscopic foci of STIC without signs of stromal invasion. Given this finding, breast imaging tests and a genetic study of the BRCA 1/2 mutation was requested. CONCLUSION: Prophylactic bilateral salpingoophorectomy in gynecological surgery is a procedure that can reduce the risk of developing peritoneal, tubal, and serous ovarian carcinomas. Patients diagnosed with STIC should be subsidiaries of follow-up based on ultrasound controls, mammary imaging tests, tumor markers, and genetic studies, due to their association in many cases with mutations in the BRCA 1/2 genes. It is necessary to establish a series of standardized clinical protocols for the management of patients with STIC and to continue advancing our understanding of this pathology and its subsequent evolution to high-grade serous carcinoma.
RESUMO
Se realizó un estudio descriptivo y transversal de 25 pacientes, adictos al tabaco, con carcinoma in situ en la mucosa bucal, atendidos en la consulta estomatológica del Policlínico de Especialidades perteneciente al Hospital Provincial Docente Clinicoquirúrgico Saturnino Lora Torres de Santiago de Cuba, desde abril del 2008 hasta igual periodo del 2013, a fin de evaluar los resultados del diagnóstico clínico e histopatológico de esta neoplasia. Mediante la técnica clásica de inclusión en parafina se confirmó la existencia de cambios celulares. En la casuística prevalecieron el sexo masculino y la ausencia de síntomas subjetivos en la forma leucoplásica. El sitio anatómico más susceptible correspondió al borde lateral de la lengua. Entre las alteraciones hísticas más comunes figuraron: hipercromatismo nuclear, membrana basal intacta, pérdida de la polaridad, así como pleomorfismo nuclear y celular(AU)
A descriptive and cross-sectional study of 25 patients, with tobacco addition and carcinoma in situ of the oral mucous, assisted in the stomatological department of the Specialties Polyclinic belonging to Saturnino Lora Torres Teaching Provincial Clinical Surgical Hospital in Santiago de Cuba was carried out from April, 2008 to same period of the 2013, in order to evaluate the results of the clinical, histological and pathological diagnosis of this neoplasia. By means of the classic technique of inclusion in paraffin the existence of cellular changes was confirmed. The male sex and the absence of subjective symptoms prevailed in the leucoplasic form in the case material. The most susceptible anatomical site corresponded to the lateral border of the tongue. Among the most common tissue alterations there were: nuclear hyperchromatism, intact basal membrane, loss of the polarity, as well as nuclear and cellular pleomorphism.

RESUMO
OBJETIVO: A incidência de carcinomas espinocelulares anais vem aumentando nos doentes HIV-positivos. O tratamento consiste de radio e/ou quimioterapia, eventualmente seguidos pela ressecção do tumor. O objetivo é avaliar o seguimento desses doentes para verificar as recidivas e a evolução do NIAA para câncer. Apresentação da casuística da Equipe Técnica de Proctologia do Instituto de Infectologia Emílio Ribas, de São Paulo. MÉTODOS: Acompanhamos 45 doentes HIV-positivos portadores de carcinoma espinocelular anal e seu precursor no período de 1996 a 2006. Eram 30 neoplasias intra-epiteliais anais de alto grau (NIAA), tratadas com ressecção local e 15 carcinomas invasores do canal anal. Nove das 15 lesões invasivas foram submetidas ao esquema de Nigro isolado ou associado à ressecção local, amputação abdominoperineal ou colostomia para derivação. RESULTADOS: No seguimento ambulatorial das NIAA tivemos recidiva em 16,7 por cento e não observamos evolução para carcinoma, num período mínimo de três anos. Entre os nove tumores submetidos ao esquema de Nigro, com ou sem operação complementar, cinco estão livres de tumor. Nenhum tratamento foi feito em cinco doentes. Em três, devido às péssimas condições clínicas, e em dois, pois recusaram tratamento. Outro teve diagnóstico na vigência de oclusão intestinal sendo submetido à colostomia de derivação. CONCLUSÃO: Concluímos que a NIAA pode reincidir após excisão local em doentes HIV-positivos, mas não evolui para carcinoma invasor e que os doentes de câncer anal invasor podem ser tratados da mesma maneira que a população soronegativa para o HIV desde que as condições clínicas o permitam.
OBJECTIVE: Incidence of anal squamous cell carcinoma is increasing mainly among HIV-positive patients. Treatment consists of radiotherapy and chemotherapy, sometimes followed by tumor resection. The objective was to evaluate the follow-up of such patients to verify recurrences and evolution from HAIN to cancer. This is a report of cases treated at the "Instituto de Infectologia Emílio Ribas", Sao Paulo, Brazil. METHODS: We attended 45 HIV-positive patients between July 1996 and June 2006. Most were male (97.7 percent), with ages ranging from 23 to 55 years (mean: 38.5 years). Thirty patients had high grade anal intra-epithelial neoplasia (HAIN), treated with local resection, and 15 with anal canal invasive squamous cell carcinoma were first submitted to chemo radiation, while biopsies were obtained during follow-up. RESULTS: Patients with HAIN had recurrences in 16.7 percent of cases and remained cancer free for up to five years. Chemoradiation was not possible in five patients with invasive carcinoma (40 percent) because three had advanced AIDS and two refused treatment. Eight (88.8 percent) out of nine patients had complete response to chemoradiation and remained cancer free for a period from three to six years. Chemoradiation failed in the ninth patient: abdominal perineal resection was performed, and there was no recurrence over a five-year period. CONCLUSION: We concluded that HAIN can recur after local resection in HIV-positive patients but does not evolve to invasive carcinoma. Invasive cancer can be treated in the same way as in HIV seronegative persons, when clinical conditions permit.
