Fat‐poor leiomyomatous angiomyolipoma arising from renal parenchyma negative for HMB‐45: A case report

Abstract

Abstract Fat‐poor leiomyomatous angiomyolipoma, which is similar to smooth muscle tumors, is positive for smooth muscle markers and melanocytic marker human melanin black 45 (HMB‐45). We report a case of fat‐poor leiomyomatous angiomyolipoma arising from renal parenchyma negative for HMB‐45 diagnosed by combined staining with melanocytic markers HMB‐45 and Melan‐A.
