Liver cell adenoma: A case report and a review of 30 cases reported in Japan

Abstract

A 38 year old man with a huge liver cell adenoma extending to the pelvis was treated by left lateral lobectomy. The tumour, which was well‐encapsulated by fibrous membrane, was 18 × 19 × 6 cm in size and weighed 1500g. Histopathologically, this tumour was composed of well‐differentiated liver cell trabeculae and a small number of pseudobiliary ducts, but no Glisson sheaths. For the past 4 years 8 months he has remained asymptomatic. Thirty cases of liver cell adenoma found in Japanese literature are reviewed here and possible pathogenic implications are discussed.
