We report the case of a 70-year-old female patient with an unclear liver mass after clinical and radiological evaluation. In histopathological evaluation, we diagnosed a hepatic angiomyolipoma, which is a rare entity and belongs to the perivascular epithelioid group of tumours (PEComa). In this report, we illustrate the typical histomorphology, immunohistochemical profile and molecular changes based on the case presentation and discuss and review the current literature on hepatic angiomyolipomas. In addition, typical differential diagnostic problems are highlighted.
