Perivascular epithelioid cell tumor (PEComa) in the genitourinary tract.
Perivascular epithelioid cell tumors (PEComas) are mesenchymal tumors composed of histologically, immunohistochemically, ultrastructurally, and genetically distinctive cells. PEComas have been described in different organs and are considered ubiquitous tumors. In this review we discuss recent informations related to PEComas in the genitourinary tract.

متن کاملA Gastric Perivascular Epithelioid Cell Tumor: A Case Report
Perivascular epithelioid cell tumors (PEComas) of gastro intestinal tract are very rare, with only few cases reported in the literature. The PEComas are a family of rare mesenchymal tumors characterized by perivascular epithelioid cell differentiation. We herein report our experience with a patient who had a primary gastric PEComa that was diagnosed by an expert pathologist review of the excise...
متن کاملEvidence on the neural crest origin of PEComas.
The perivascular epithelioid cell (PEC) has been proposed to be the proliferating cell type in a group of tumors known as PEComas. The histogenesis of PEComas is one of the most mysterious aspects of pathology. Hypothesis on its precursor are many, including a cell from blood vessel walls or the myoblast. In the current report, we review many morphologic, clinical, ultrastructural, molecular an...
