Hepatic angiosarcoma: report of a case without a history of exposure to environmental risk factors

ABSTRACT

A 30 year-old male patient was referred with RUQ abdominal pain of 10 months duration. With the impression of acute abdomen, the patient underwent surgery. The pathologist proposed hydatid cyst as the probable diagnosis. Because of persisting abdominal pain the patient was reevaluated. CT scan showed a mass lesion, 22cm in diameter, in the right hepatic lobe and thus right hepatic lobectomy and cholecystectomy were performed. Histologic findings were consistent with angiosarcoma. Increased familiarity with this cancer will facilitate correct diagnosis and will help to differentiate it from the more prevalent hepatic mass lesions found in Iran
