While liver hemangioma and focal nodular hyperplasia are not considere
d an indication for surgery in asymptomatic patients resection has bee
n recommended for hepatocellular adenoma because of the risk of ruptur
e and malignant transformation. Problems arise from differential diagn
osis and the appropriate surgical radicality including the indication
for liver transplantation. This retrospective analysis deals with 58 p
atients who underwent surgery for hepatocellular adenoma: resection of
different extension: n = 54, liver transplantation n = 4. In 39.6 % o
f the patients the tumor was an incidental finding. In 62.0 % the char
acter of the lesion was unclear prior to surgery. Tumor rupture and bl
eeding occurred in 17.2 %, malignant transformation in 6.9 %. Surgical
morbidity was 27.6 %, mortality 5.2 % with the transplant patients al
ive for 1.5, 7, 9 and 10 years. Two and five years after resection 2 p
atients developed hepatocellular carcinoma in the liver remnant. The r
esults confirm the indication for surgery in hepatocellular adenoma. D
iagnostic approach for solid liver tumors without serum increase of tu
mor markers should rule out FNH and hemangioma. In all other patients
surgery should be considered whenever possible with the radicality of
malignant disease. Liver transplantation can be discussed Even in asym
ptomatic patients with multiple adenoma.
