title: [The malignant potential of adenofibroma and cystadenofibroma of the ovary and mesovarium. 118 cases including 13 proliferative and 5 carcinomatous].
abstract: The relationship between adenofibroma and cystadenofibroma and the frequency and features of carcinomas developed on these benign tumours are little known. Eight-hundred and forty-five epithelial tumours of the ovary diagnosed over a 10-year period have been re-examined. One-hundred and eighteen adenofibromas and cystadenofibromas were recorded. One-hundred were benign and formed an architectural spectrum from which emerged: (1) surface papillary adenofibroma accounting for 5% of the cases and appearing at a mean age of 27 years; (2) cystadenofibroma in 77.5% of the cases at a mean age of 53 years; (3) adenofibroma in 17.5% of the cases at a mean age of 64 years. Adenofibroma was bilateral in 18 cases. Among the other cases were an endometrioid cyst and two simple serous cysts. The cells were serous in 110 cases, mucinous in 6 cases and weakly acidophilic to clear in 2 cases. Eighteen of these tumours were malignant: 13 were associated with epithelial hyperplasia and 5 with a carcinoma. The 13 adenofibromas with atypical epithelial hyperplasia (at a mean age of 60 years) were all made of serous cells; 6 of them were low-grade and 7 high-grade tumours with 3 microinvasions. One patient died at the age of 78, of an unknown cause; the others are still alive after a mean follow-up of 11.3 years. The 5 invasive carcinomas appeared on an adenofibroma at the mean age of 70 years; 3 patients died (2 of metastases), one is alive after 9 years and one was loss sight of.(ABSTRACT TRUNCATED AT 250 WORDS)
