Abstract
Abstract
Perivascular epithelioid cell tumor (PEComa) is a neoplasm chiefly composed of HMB-45–positive epithelioid cells with clear-to-granular cytoplasm and a perivascular distribution. We describe such a tumor involving the prostate and seminal vesicle in a 46-year-old man. The tumor had characteristic histologic features of PEComa. Immunohistochemically, the tumor cells were positive for HMB-45 but negative for epithelial markers, Melan-A, and S100 protein. The tumor behaved in a malignant fashion, and the patient died of the disease 4 years after diagnosis.
