Perivascular epithelioid cell tumours (PEComas) belongs to the family of mesenchymal neoplasms that can occur in many organs, but rarely found in liver. Preoperative diagnosis could be challenging due to unspecific and variable radiologic patterns, which can be clinically misdiagnosed with hepatocellular carcinoma and other benign tumors. This report aims to announce a case of hepatic PEComa with extramedullary hematopoiesis. A 44- year- old woman accidentally presented a nodular mass in the left hepatic segment on ultrasonography with normal liver function result. Abdominal enhanced CT Scan showed hypervascular lesion. Morphology exibits classical characteristics of PEComa with mature fat tissue predominance, thick-wall vessel; somewhat amount of extramedullary hematopoiesis was also recognized. Tumor cells are diffusely immunoreactive with HMB45. PEComa is a rare disease in liver, pathologists need to recognize three components of this tumor to avoid misdiagnosing with malignant conditions.
