Hepatic angiomyolipoma-misdiagnosis as hepato- cellular carcinoma: A report of 14 cases

摘要

Angiomylolipoma (AML0 is a rare benign mesenchymal tumor of the liver, composed of a varying heterogeneous mixture of three tissue components: blood vessels, smooth muscle, and adipose cells. It has recently been proposed that the perivascular epithelial cell (PEC) is the common progenitor. Since its first description by Ishak in 1976~[3], there have been more than 100 cases reported in the English literature. With the advance of radiological techniques, many more tumors are being diagnosed by the means.
