A Case of Polycystic Liver Disease with Intractable Infection Associated with Adenocarcinoma

Abstract

A 62-year-old man who had received puncture, drainage and injection of ethanol for several times for multiple liver cysts which tended to enlarge at previous hospital developed infection of the treated cysts that acquired resistance against medical treatment. He was thus referred to our hospital. When he was first seen at our hospital, a drainage tube had been placed in the infected liver cyst in the hepatic right lobe, small quantities of bloody discharge persisted, and skin damage was associated. Right lobectomy of the liver was performed with a diagnosis of infected liver cyst and the drainage tube could be removed. The postoperative course was uneventful and he was discharged from our hospital. The wall of the infected hepatic cyst was white and thickened, and a intramural solid component was present. Histopathological studies revealed adenocarcinoma within the cyst and along the fistula. It has rarely been reported that polycystic liver disease is associated with a malignant neoplasm, but a possibility of the association must be kept in mind when an infected liver cyst is intractable for a long time.
