Abstract
In these days of highly-spread medical care, it is comparatively rare to encounter giant ovarian cystoma. The authors have recently experienced three cases of pseudomuciloginous cystadenoma in patients of middle and advanced ages. The weights of tumor are from 6.2 to 13.6 kg and their abdominal cavities are filled with the adenoma. The authors take this opportunity to investigate the giant ovarian cystoma clinically.
