Abstract

An adult male blue Siamese fighting fish (Betta splendens) presented to the North Carolina State University College of Veterinary Medicine with a cranial mass located dorsal to his right eye. A fine-needle aspiration was performed followed by supportive care. Due to the patient’s small size aggressive treatment was not elected. The mass continued to expand over a course of five months until the patient was found deceased, and a postmortem examination was performed. Histopathology determined the mass to be a chromatophoroma of the iridophoroma or leucophoroma subtypes. This is the first documentation of a chromatophoroma in B splendens.
