Summary
Hepatoma, a type of liver cancer, was identified in rainbow trout from Sofia fish farms. This finding suggests similarities between fish liver tumors and those in birds and mammals.
Area of Science:
- Veterinary Pathology
- Aquatic Animal Health
- Oncology
Context:
- Hepatoma cases were documented in rainbow trout (Salmo irideus) from three fish-breeding farms in the Sofia region.
- The study investigated the histological and gross pathological features of these liver tumors.
Purpose:
- To describe and characterize hepatoma in rainbow trout.
- To compare liver tumors in fish with those in other animal classes.
Summary:
- Histological examination revealed tumor cells arranged in trabeculae, paths, or focal distributions.
- Tumorous growths exhibited trabeculous or alveolar structures, with some neoplasms showing carcinomatous characteristics.
- The tumor stroma varied from weakly developed to a rich fibrous stroma, with observed infiltrative growth.
Impact:
- The findings indicate that hepatoma in rainbow trout shares similarities with liver tumors observed in birds and mammals.
- This research contributes to understanding comparative oncology in aquatic animals.
- Highlights the importance of monitoring liver health in farmed fish populations.
