Roughly 1% of mature cystic teratomas undergo malignant transformation. In particular, cutaneous-type adnexal neoplasms may occur in mature cystic teratomas. Sebaceous carcinomas, which arise from mature cystic teratomas, have rarely been observed, with only seven cases previously reported. Here, we present a case of a 69-year-old female who had pelvic pain for two weeks and who subsequently underwent bilateral salpingo-oophorectomy and hysterectomy. Her left ovary showed a unilocular cyst, measuring 22.0 cm in diameter, filled with sebaceous material and a few hairs. A luminally-protruding solid mass measuring 4.0 cm in diameter was also noted. Microscopic findings revealed lobular or diffusely arranged basophilic, atypical sebaceous cells connected to a typical mature cystic teratoma. Tumor cells demonstrated positive immunoreactivity for high molecular weight cytokeratin, cytokeratin 7, cytokeratin 19, epithelial membrane antigen, and carcinoembryonic antigen. Here, we present a case of sebaceous carcinoma arising from a mature cystic teratoma along with a review of previously published reports.

Abstract PDF

BACKGROUND
Stromal cells (SCs) of hemangioblastomas (HBs) have been regarded as true neoplastic components, but their ontogeny remains unclear. Convincing evidence suggests that embryonic mesenchymal cells may be the cells of origin of HBs. The aim of the present study was to investigate the immunophenotypic characteristics of neoplastic SCs using a set of markers against endothelial cells (ECs), vascular smooth muscle cells (vSMCs), mesenchymal stromal cells (MSCs), and pericytes.
METHODS
Intracranial HBs (n=46), angiolipoma (n=9), and pyogenic granuloma (n=11) were retrieved and the immunophenotypic profile of SCs was determined by immune stainings.
RESULTS
The MIB-1 labeling index was significantly higher in SCs compared to that of ECs and vSMCs, regardless of the type of lesion. The neoplastic SCs of HBs consistently expressed both MSC and pericyte markers, but did not express markers of ECs and vSMCs. Double immunofluorescent staining demonstrated that the neoplastic SCs of HBs expressing MSC or pericyte markers directly abutted onto the ECs of capillaries/venules.
CONCLUSIONS
The results suggest that the neoplastic SCs of HBs share the immunophenotypic profile and distribution with those of pericyte-derived MSCs. Thus, HBs might originate from a distinctive population of pericyte-derived MSCs in the central nervous system.
