Ovarian atypical proliferative (Borderline) Brenner tumor

Öz

Brenner tumors are rare transitional cell tumors of the ovary. They are usually benign tumors but rarely have borderline and malignant types. Most of the benign Brenner tumors are small and are found incidentally. Our case was a 57 years old woman who underwent laparotomy for ovarian cyst. On laparotomy a solid mass was found on the left ovary. The left ovarian mass was excised and a histopathological diagnosis of borderline (atypical proliferative) Brenner tumor was made. In this paper, histopathological findings of this rare case are presented and the literature is reviewed.

Overin atipik proliferatif (Borderline) Brenner tümörü

Öz

Brenner tümörleri overin nadir görülen transizyonel hücreli tümörleridir. Genellikle benign tümörlerdir ancak daha ender olarak borderline ve malign tipleri de vardır. Benign Brenner tümörlerinin çoğu küçüktür ve rastlantısal olarak bulunur. Olgumuz sol over kisti nedeni ile laparotomi yapılan 57 yaşında kadın hastadır. Sol overdeki kitle eksize edildi ve histopatolojik incelemede borderline (atipik proliferatif) Brenner tümörü tanısı konuldu. Yazımızda bu nadir olgunun histopatolojik bulguları sunularak literatür gözden geçirilmektedir.
