title: [Acute abdomen as form of presentation of hepatic adenoma].
abstract: We report the case of a woman aged 33 years old who was admitted with an acute abdomen. She referred oral contraceptives intake. Physical findings were abdominal tenderness, involuntary guarding and right upper quadrant rigidity. The following studies were performed: laboratory tests excluded hydatidosis and amebiasis. Ultrasonography showed a nodular image in the right hepatic lobe and a normal biliary tract. A low-density mass was observed with the computed tomographic scanning. A tomographic guided needle biopsy was informed as normal liver cells. Angiography showed tortuous hepatic arteries. Laparoscopy revealed a solid formation blood was obtained when it was punctured. Laparotomy was indicated. A tumor in the right hepatic lobe was found but a surgeon did not resect the lesion because a congelation biopsy failed to demonstrate tumoral cells. The diagnosis of hepatic adenoma was reached with the definitive biopsy. Our patient had a good evolution with the contraceptives withdrawal and a tomographic scanning one year after surgery showed the almost complete remission of the tumor. Pain as the initial symptom was observed in 12-52% of patients with an hepatic adenoma an audden onset in 33% of them. However this tumor is not frequently considered as a cause of acute abdomen.
