ABSTRACT
The World Health Organization (WHO) defines a perivascular epithelioid cell tumor (PEComa) as a mesenchymal neoplasia composed of perivascular epithelioid cells with characteristic morphological and immunohistochemical features. They are rarely malignant. Indeed, only a few cases have been reported in the English literature, and this is the first case of PEComa reported in Korea. A 64-year-old man presented with an abdominal mass and peritoneal seeding. The patient underwent mass excision with descending colon resection and anastomosis. The primary mass and peritoneal seeding was diagnosed as a PEComa histopathologically. Seven months later, he developed liver metastasis and aggravated peritoneal seeding. Here, we report a case of malignant PEComa of the omentum.
