A moribund four years old Goldfish (Carassius auratus), was referred veterinary hospital of Shahid Chamran University of Ahvaz with an exophytic non-ulcerated mass near the caudal peduncle. Microscopic examination of the mass revealed proliferated spindle cells and the interlacing, loose and eosinophilic bundles.
