Perivascular epithelioid cell tumors (PEComas) are a group of rare mesenchymal neoplasms which composed of histologically and immunohistochemically distinctive perivascular epithelioid cells (PECs). In recent years, PEComas have been manily reported in liver, kidney, lung, uterus and adnexa,1 but rare in small or large intestine.2-6 Here, we describe a case of PEComa restricted in the cecal mucosa, which displayed histological characteristics of epithelioid clear cells.
