Perivascular epithelioid cell neoplasm

定义 英文原文（暂无中文）

A rare soft tissue tumor characterized by distinctive perivascular epitheloid cells, often arranged radially around a vascular lumen, as well as spindled cells in variable proportion. Melanocytic and muscle markers are typically positive. The tumors have been reported in the uterus, falciform ligament, and large and small intestine, among others. Depending on their location, they may present as a painful or painless mass, or with vaginal bleeding. Tumors displaying infiltrative growth, marked hypercellularity, nuclear enlargement and hyperchromasia, high mitotic activity, atypical mitotic figures, and/or coagulative necrosis should be regarded as malignant.
