Abstract
Twenty-four patients with liver cell adenomas were referred to Paul Brousse Hospital between 1976 and 1987. This represents the largest reported surgical experience of this pathology from a single centre. Six patients had multiple adenomas, which were associated with glycogen storage disease in four. Two patients had polyadenomatosis, one of whom underwent successful liver transplantation after malignant transformation to hepatocellular carcinoma. Eighteen patients (median age of 33 years, range of 17-45 years) had either a solitary adenoma or two adenomas. Eighty-three per cent were women 97% of whom had received oral contraceptives or other hormone therapy before diagnosis (median duration of 11 years, range of 3-15 years). Fifty per cent of these patients presented with acute hemorrhage into an adenoma. Seventeen patients underwent surgical resection of their adenomas, with the remaining patient currently being treated by arterial embolizations to reduce the tumor size before surgery. There was no operative mortality or serious morbidity, and all patients remain well upon follow-up. Surgical excision of liver adenomas, where this can be done without causing mortality, is recommended. Resection relieves symptoms and removes both the risks of hemorrhaging into the tumour and of malignant transformation to hepatocellular carcinoma.
