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.
The authors present the report of the first ever case of angiomyolipoma arising in the larynx. The tumor was found in a 61-year-old man and was resected through laryngofissure. Histopathologic examination of the tumor revealed numerous smooth muscle cells, mature adipose tissue and numerous thin and large irregular vessels. Both histological and immunohistochemical findings were typical for tumors of the mucocutaneous angiomyolipoma group.
