Perivascular epithelioid cell tumor of the descending colon mimicking a gastrointestinal stromal tumor: a case report
BACKGROUND We present a case of perivascular epithelioid cell tumor (PEComa), which clinically and histologically mimics a gastrointestinal stromal tumor (GIST). CASE PRESENTATION A 42-year-old woman was found to have a mass in the left flank during her annual medical checkup. Computed tomography examination revealed a submucosal tumor of the descending colon. Surgeons and radiologists suspec...
متن کاملA Gastric Perivascular Epithelioid Cell Tumor: A Case Report
Perivascular epithelioid cell tumors (PEComas) of gastro intestinal tract are very rare, with only few cases reported in the literature. The PEComas are a family of rare mesenchymal tumors characterized by perivascular epithelioid cell differentiation. We herein report our experience with a patient who had a primary gastric PEComa that was diagnosed by an expert pathologist review of the excise...

Perivascular epithelioid cell tumors (PEComa) are tumors of perivascular epithelioid cells with immunohistochemical features of smooth muscle and melanocytic tumors.

متن کاملPerivascular epithelioid cell tumor (PEComa) in the transverse colon of an adolescent: a case report.
Perivascular epithelioid cell tumor (PEComa) is defined as a very rare mesenchymal tumor of histologically and immuno-histochemically distinctive perivascular epithelioid cells. PEComa in the colon is very rare, with only a few reported cases so far. Because of its rarity, the clinical features and biological behavior of PEComa in the colon have yet to be established. A 16-year-old female patie...
متن کاملMicroscopic endometrial perivascular epithelioid cell nodules: a case report with the earliest presentation of a uterine perivascular epithelioid cell tumor
Perivascular epithelioid cell (PEC) tumors (PEComas) are a family of related mesenchymal tumors composed of PECs which co-express melanocytic and smooth muscle markers. Although their distinctive histologic, immunohistochemical, ultrastructural, and genetic features have been clearly demonstrated, their histogenesis and normal counterpart remain largely unknown. Precursor lesions of PEComas hav...
