title: Coexisting adenocarcinoma and cystadenofibroma (malignant cystadenofibroma) of the ovary.
abstract: We have described an adenocarcinoma observed as a grossly discrete area within a cystadenofibroma of the ovary. Fewer than 35 cases of malignant cystadenofibroma have been reported. We find our observations lend support to the prevailing thought that these neoplasms most often originate from preexisting cystadenofibromas.
