Summary
A 15-year-old bittern presented with weight loss and ascites. Necropsy revealed a large abdominal carcinoma, likely originating from the gizzard, with metastasis to the liver and intestines.
Area of Science:
- Avian Pathology
- Wildlife Medicine
- Comparative Oncology
Background:
- Bitterns are rare wetland birds facing various health challenges.
- Neoplastic diseases can significantly impact wildlife populations.
- Ascites and weight loss are common clinical signs in sick birds.
Purpose of the Study:
- To document a case of abdominal carcinoma in a bittern.
- To describe the gross and histological findings of the tumor.
- To contribute to the understanding of avian neoplasms.
Main Methods:
- Necropsy examination of a deceased bittern.
- Gross pathological assessment of abdominal organs.
- Histopathological analysis of neoplastic tissue.
- Microscopic evaluation for mitotic figures and tumor architecture.
Main Results:
- A large, invasive carcinoma was identified in the abdominal cavity, attached to the gizzard and involving the liver and intestines.
- Histological examination revealed numerous mitotic figures and an acinar pattern, consistent with carcinoma.
- Severe hepatic haemosiderosis and incidental renal cysts were also noted.
Conclusions:
- The findings indicate a primary abdominal carcinoma in the bittern, likely of gizzard origin.
- This case highlights the potential for aggressive neoplasms in avian species.
- Further research into avian cancers is warranted to improve conservation and veterinary care.
