Abstract

Haemangioma is a benign tumor of vascular endothelial cells or their progenitors. In spring of 2016, an <em>Acipenser baerii</em>, (+3 years, 2.2 kg weight) was reffered to the Department of Aquatic Animal Health, Faculty of Veterinary Medicine, Shahid Chamran University of Ahvaz. After dissection it was found that the heart had a cobblestone appearance which was characterized by multiple dark red cysts with different sizes (2-5 mm). According to microscopic results, epicardial cavernous hemangioma was diagnosed. To the best of the author's knowledge, this is the first report of primary epicardial cavernous hemangioma in <em>Acipenser</em> <em>baerii</em>.<br /> <strong> </strong>
