ABSTRACT
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.
