Carcinoma intraepitelial tubárico seroso como hallazgo posquirúrgico de endometriosis y útero miomatoso. Reporte de un caso / Seuous tubal intraepithelial carcinoma as a post-surgical finding of endometriosis and myomatous uterus. A case report

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.

Pathologic findings at risk-reducing salpingo-oophorectomy (RRSO) in germline BRCA mutation carriers with breast cancer: significance of bilateral RRSO at the optimal age in germline BRCA mutation carriers / 부인종양

OBJECTIVE: Most BRCA1/2 carriers do not undergo risk-reducing salpingo-oophorectomy (RRSO) by the recommended age. This study aimed to find the incidence of precursor lesions and cancer after RRSO. METHODS: We retrospectively reviewed breast cancer patients identified as BRCA mutation carriers who underwent RRSO at Asan Medical Center, Seoul, Korea, from 2010 to 2014. From 2013, all cases were examined according to the Sectioning and Extensively Examining the Fimbria (SEE/FIM) protocol and underwent immunohistochemically staining. RRSO was performed in 63 patients, 27 in 2010 to 2012 and 36 in 2013 to 2014. RESULTS: The median age at RRSO was 46.5 years (range, 32 to 73 years). Occult invasive cancer was detected in eight patients, of ovarian origin in five and of tubal origin in three. All occult invasive cancer cases with metastasis were detected in patients older than 40 years. Of the 36 patients from the 2013 to 2014 cohort, seven showed p53 overexpression, one showed Ki-67 overexpression, two showed serous tubal intraepithelial carcinoma, and three showed occult cancer. The detection rate of precursor lesions or cancer was 36.1% (13/36). In the analysis according to age, precursor lesions were more common in BRCA1 mutation carriers younger than 40 years old (66.7% vs. 20.0%). In BRCA2 mutation carriers, precursor lesions were only detected in those older than 40 years of age, indicating the possible faster occurrence of precursor lesions in BRCA1 mutation carriers. CONCLUSION: Many patients still tend to delay RRSO until after they are 40 years old. Our findings support the significance of RRSO before the age of 40 in germline BRCA mutation carriers.

Secretory cell outgrowths, p53 signatures, and serous tubal intraepithelial carcinoma in the fallopian tubes of patients with sporadic pelvic serous carcinoma.

Context: High‑grade serous carcinomas of ovarian, tubal, and peritoneal origin are together referred as pelvic serous carcinoma. The fallopian tubes, ovarian surface epithelium, and the tuboperitoneal junctional epithelium are all implicated in pelvic serous carcinogenesis. Aims: The aim of this study is to identify putative precursor lesions of serous carcinoma including secretory cell outgrowths (SCOUTs), serous tubal intraepithelial carcinoma (STIC), and p53 signatures and assign its probable site of origin. Settings and Design: Prospective case–control study of consecutive specimen comprising 32 serous carcinomas and 31 controls (10 normal adnexa, 10 benign and 6 atypically proliferative surface epithelial tumors, and 5 other carcinomas). Subjects and Methods: Sectioning and extensive examination of the fimbrial end (SEE‑FIM) protocol along with immunohistochemistry for Bcl‑2, p53, and Ki‑67 was employed for evaluating invasive carcinoma and precursor lesions in cases versus controls. Results: SCOUT, p53 signatures, and STIC were most frequent in the serous carcinomas. p53 signatures and STIC were always seen in the fimbrial end. STICs were exclusively present in serous carcinomas, more common in ipsilateral tubes of cases with dominant ovarian mass. Multifocal p53 signatures with STIC were seen in 7 (21.9%) cases. STIC was present with or without an invasive carcinoma in 25% and in 6.25% of cases of pelvic serous carcinomas, respectively. The junctional epithelia did not show any lesion in any group. Conclusions: SEE‑FIM protocol is recommended for evaluation of sporadicpelvic (ovarian/tubal/peritoneal) serous carcinoma. Based on the presence of STIC or invasive carcinoma, nearly 60% of all pelvic serous carcinomas are of fallopian tubal origin.

Neoplasia intraepitelial córneo-conjuntival. A propósito de un caso / Corneal -conjunctival intraepithelial neoplasia. A propos of a case

La neoplasia intraepitelial córneo-conjuntival, es una entidad nosológica muy poco frecuente en la consulta de Oftalmología del Hospital Universitario Clínico Quirúrgico Comandante Faustino Pérez Hernández, de Matanzas. Sin embargo, en el presente año se han diagnosticado, según estadísticas e informe de anatomía patológica, tres casos en dos de las consultas especializadas, lo que motivó la presentación de este caso. Se trata de un paciente de 81 años de edad, que acudió a consulta en el mencionado hospital en el mes de marzo de 2011, pues desde hacía seis meses presentaba enrojecimiento de su ojo derecho. Al examen oftalmológico se constató lesión blanquecina, nodular de bordes irregulares, que se extendía desde conjuntiva bulbar externa a limbo y tercio externo de la córnea con tres lesiones satélites nodulares en región paracentral. Se le realizó el diagnóstico de neoplasia intraepitelial córneo-conjuntival, que fue corroborado mediante el estudio anátomo-patológico de la biopsia. En estos momentos se mantiene asintomático, con evolución satisfactoria.

We expose the case of a patient, aged 81 years old, a fisherman, who assisted the consultation of the Teaching Clinico-surgical Hospital Comandante Faustino Pérez Hernández, of Matanzas, in March 2011, because of a reddening of his right eye during the last six months. At the ophthalmologic examination we found a whitish, nodular lesion with irregular edges extended from the external bulbar conjunctive to the limbus and external third of the cornea with three satellital nodular lesions in the paracentral region. We diagnosed a corneal-conjunctival intra-epithelial neoplasia, being corroborated through the anatomopathologic study of the biopsy. Currently he is asymptomatic, with a satisfactory evolution.

Squamous Cell Carcinoma of the Cervix with Intraepithelial Extension to the Endometrium: A Case Report

Squamous cell carcinoma (SCC) of the cervix with intraepithelial extension to the endometrium is a rare event, accounting for about 0.7% of all cervical SCC. Endometrial lesion has been considered as a direct extension of cervical cancer in the early reports, and this was confirmed in a recent molecular study. I report here on the case of a 56-year-old woman who had stage IIB SCC of the cervix with extension, in an in situ fashion, to the entire endometrium. HPV type 16 was detected via PCR in both the cervical and endometrial tumors.
