Namazi F, Mosleh N., Intestinal metastasis of ovarian adenocarcinoma in a hen (Gallus domesticus), Onl J Vet Res., 27 (2): 123-128, 2023. Laying hens develop spontaneous ovarian cancer similar to humans. Reports of natural or non-viral occurring neoplasms among avian species is sparse. In a flock of 30 layers mortality rate was 13.3% with associated drop in egg production. An aged dead adult native hen was referred for necropsy. Grossly, pedunculated, firm, greyish-white fleshy growths were found attached to the serosal surface of ovary together with spread over the whole of intestine serosa. Microscopically, the ovarian growths consisted of a tubular pattern confirmed as adenocarcinoma with metastasis on the intestines.
Key words: ovarian adenocarcinoma; metastasis; intestine; pathological findings.
