[Two cases of huge hepatic hemangioma].

We have experienced two cases of huge hepatic hemangioma. Case 1 was a 51-year-old man complaining of abdominal fullness and was shown low density area in the right hepatic lobe by abdominal computed tomography. He was treated with segmentectomy of the right hepatic lobe. The resected specimen was histologically diagnosed as cavernous hemangioma. Case 2 was a 61-year-old man who showed no symptom and was shown 10 x 6.5 cm hemangioma by abdominal ultrasonography. He have been untreated. For 10 years, 29 cases of huge hepatic hemangioma, including our two cases have been reported in Japan. The female to male ratio is 5:1. The incidence of huge hepatic hemangioma was frequent in the fifth and sixth decades of life. The majority of patients complained of palpable abdominal mass and abdominal pain. The dominant site of huge hepatic hemangioma was the anatomical right hepatic lobe.
