INTRODUCTION
Hepatic angiomyolipomas are rare
mesenchymal neoplasms composed of an admixture of smooth muscle cells,
adipose tissue, and blood vessels [1]. Epithelioid angiomyolipoma is
a rare variant of angiomyolipoma where the epithelioid smooth muscle
cells predominate [2]. Due to their varying composition,
particularly their frequent paucity of fat, diagnosis can be challenging
both radiologically and histologically resulting in misdiagnosis prior
to excision [3]. Herein, the authors report a new case of hepatic
epithelioid angiomyolipoma with a minor adipocytic component mimicking a
hepatocellular carcinoma. They describe its histopathological
characteristics illustrating the wide variety of its appearances, and
highlight the challenges and potential errors that can be made.
