title: [Renal epithelioid angiomyolipoma mimicking renal carcinoma].
abstract: Epithelioid angiomyolipoma is a rare form of potentially malignant angiomyolipoma, recently considered separate entity by the World Health Organization classification of renal tumors. This lesion poses a problem in differential diagnosis with clear cell carcinomas. There are no clinical or radiological specific criteria that characterize this tumor. Immunohistochemistry revealing epithelioid cells with positive HMB45 marker is essential for diagnosis. Treatment should be discussed during the multidisciplinary consultation.
