AB Under 10% of gynaecological cancers are diagnosed in the vulva and vagina, mostly squamous cell carcinomas. Melanoma, Paget disease, basal cell carcinomas, and other cancers can present with vulval/vaginal symptoms.

AB Sebaceous carcinoma (SC) is a malignant neoplasm demonstrating sebocytic differentiation, commonly in the periocular area. Sebocytic differentiation is recognized by multivesicular cytoplasmic clearing with frequent nuclear scalloping.

AB We describe a very unusual cervical tumor in a 12-yr-old patient with a clinical history indicative of DICER1 syndrome. Morphologic, immunohistochemical, and molecular genetic analysis together helped to diagnose this lesion as a cervical pleuropulmonary blastoma-like tumor, associated with TP53 and DICER1 mutations.

AB To investigate the prevalence and prognostic significance of programmed death ligand-1 (PD-L1) expression and CD8+ tumor-infiltrating lymphocytes (TILs) in gynecologic carcinosarcoma, 81 cases (68 uterine, 12 ovarian, and 1 fallopian tube) were immunostained with PD-L1 and CD8 using tissue microarrays (3 mm core diameter) from intratumoral areas with the highest TILs.

AB Cholangiocarcinoma is an uncommon and aggressive malignancy of intrahepatic and extrahepatic bile ducts. We present a case of a 37-year-old woman with cholangiocarcinoma metastatic to the endometrium that mimicked a primary endometrial adenocarcinoma at resection.

AB We report an unusual case of a pelvic extraovarian moderately differentiated Sertoli-Leydig cell tumor arising in a 4-yr-old female. The tumor contained a DICER1 pathogenic variant which was absent in the germline ruling out DICER1 syndrome. In reporting this case, we discuss the differential diagnosis and possible histogenesis and review reported cases of extraovarian Sertoli-Leydig cell tumor.
