Abstract
A 58-year-old female, who had papillary adenocarcinoma arising from unilocular cyst in the liver, underwent left lobectomy and survived for more than three years, showing the longest survival among Japanese cases of adenocarcinoma arising from liver cyst.
Malignant change of simple cyst of the liver has been considered to be very rare, but the results of our review of cases reported in Japan revealed that this condition has not infrequently been reported as cystadenocarcinoma.
From our review of Japanese literature, 33 cases of cystic adenocarcinoma of the liver including our case may be divided into the following three groups; a) adenocarcinoma arising from liver cyst, 24 cases b) cystadenocarcinoma from cystadenoma, 4 cases c) primary cystadenocarcinoma, 5 cases.
The recent development of diagnostic imaging modalities has resulted in an increases frequency of detection of liver cysts and papillary projection of liver cysts which suggest that this condition is not as rare as used to be thought. Detailed examination and follow-up are therefore thought to be necessary.
