This study was performed to determine the incidence and anatomo-pathological aspects of the reproductive system tumors in commercial laying hens. Post mortem examination of 1041 laying hens revealed neoplasms of the ovaries and the oviduct in 52 (4.99%) cases. From these, ovarian adenocarcinoma was found in 14 cases, granulosa cell tumor in 7 cases, theca cell tumor in 1 case and Marek's disease in 3 cases. Oviductal adenocarcinoam was observed in 17 cases, adenomatosis in 2 cases and leiomyoma in 8 cases. The macroscopic and light microscopic characteristics of these tumors were reported in details.
