UTERINE PERIVASCULAR EPITHELIOID CELL TUMOR:A CASE REPORT
Abstract
Perivascular epithelioid cell tumor (PEComa) is composed of HMB45+ epithelioid cells with clear to granular cytoplasm and perivascular distribution. We describe a uterine PEComa in a 33 years old woman where tumor cells were positive for HMB45 but negative for epithelial markers and negative or positive for smooth muscles markers.
