Namazi F, Mosleh N., Intestinal metastasis of ovarian adenocarcinoma (Gallus domesticus), Onl J Vet Res., 27 (10): 562-565, 2023. Laying hens develop spontaneous ovarian cancer similar to humans. However, intestinal carcinoma is unusual in chickens, and metastasis may originate from ovary or oviduct. Tumors can implant throughout abdominal cavity but trans-coelomic spread occurs infrequently. An aged dead adult native hen was referred for necropsy. Macroscopically we found pedunculated, firm, greyish-white tumors attached to ovarian serosa spread over whole of intestine serosa. We found no tumors in mucosal lining of oviduct or intestine suggesting tumor did not originate there. Microscopically, ovarian growths consisted of a tubular pattern confirmed as adenocarcinoma with metastasis on intestines. By microscopy, we diagnosed ovarian adenocarcinoma with metastasis of entire intestine. Micro and macroscopic images are provided.


Key words: ovarian adenocarcinoma; metastasis; intestine; pathology.
