METHODS Institutional review board approval was obtained for this retrospective study. Clinical data and preoperative CT images of 11 cases of E-AML were retrospectively analyzed. All patient...
متن کاملEpithelioid Angiomyolipoma of Kidneys
Renal angiomyolipoma (AML) is a benign tumor composed of fat cells, smooth muscle cells, and thick-wall blood vessels. Epithelioid angiomyolipoma (EAML) is a variant of AML and is composed of purely epithelioid cell with melanogenesis markers. Neither adipocytes nor abnormal blood vessels are noted.

متن کاملHepatic Epithelioid Angiomyolipoma: Case Series
Hepatic epithelioid angiomyolipoma (AML) is a rare, benign, mesenchymal neoplasm found in both males and females, and most commonly encountered in adult females. These lesions are difficult to diagnose by imaging, especially when fatty component is scant or absent. Histomorphologically, they resemble hepatocellular carcinoma. The tumor cells are strongly positive for homatropine methylbromide-4...
