ACCESSORY LIVER ATTACHED TO THE RIGHT LOBE OF THE LIVER

Recently we have encountered a case of accessory liver attached to the right lobe of the liver. A 31-year-old man underwent laparotomy and accessory liver attached to the segment six of the right lobe of the liver through restiform tissue, measuring 1.2×0.8×0.3cm, was found incidentally. The accessory liver was resected. Histopathologically, bile duct, portal vein and arterial branch were noted in the part of the restiform tissue and this case was interesting from the standpoint of the genetics of accessory liver. Glisson's sheath was tissue and this case was interesting from the standpoint of the genetics of accessory liver. Glisson's sheath was Accessory liver is a developmental anomaly of the liver, the incidence of which is very low, and in Japan, since when Tasaki reported in 1904, only 48 reports have been available. We discussed the age distribution, sex difference, opportunity of the diagnosis, location, size, number, pathological findings, and the communication with the primary liver in the light of these reports.
