[Giant cavernous hemangioma of the liver].

Hemangioma, the most common benign tumor of the liver, is found in 2% of all autopsies. Giant cavernous hemangiomas are those larger than 4 cm, and the only ones of clinical importance. During 1991-95 we saw 69 patients with cavernous hemangiomas of the liver ranging from 2 to 25 cm in diameter. In 62% (30 women and 13 men) they ranged from 4 to 15 cm (mean 6.3). Only 11 patients, in whom the hemangioma was symptomatic, were referred for surgery. The others were either asymptomatic or their symptoms were considered mild, and they were only followed. 4 refused surgery, but in 7 the hemangioma (ranging from 4.8 to 15.0 cm, mean 10.2) was removed; 1 required 4 units of blood. There was no mortality; complications consisted of single cases of slipped tie requiring reoperation for intraabdominal bleeding, a bile leak treated by percutaneous drainage, and delayed wound healing. After 6 months all patients were symptom-free. Our data are consistent with the present trend to operate only when a giant, cavernous hemangioma of the liver produces symptoms.
