Hepatic 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.

The tumor cells are strongly positive for homatropine methylbromide-4...

It is a special kind of angiomyolipoma that is rarely reported in the liver. Patients with HEAML may recurrence or metastasis after surgery.

متن کاملRuptured Hepatic Epithelioid Angiomyolipoma: A Case Report and Literature Review
A 38-year-old male was admitted to our hospital due to upper abdominal pain. Computed tomography revealed a hepatic angiomyolipoma (AML; 10.5 × 9.5 × 7.0 cm in size), which had ruptured into the space between the liver and the diaphragm. Following transcatheter arterial embolization, surgical resection was performed. The tumor consisted of epithelioid cells (50-60%), mature fat (40-50%), and th...
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. Pathologically, tumor cells have nuclear atypia and eosinophilic cytoplasm. EAML has a malignant...
