Medulloepithelioma of the Ciliary Body in the Goldfish(Carassius auratus)

Abstract

A medulloepithelioma of the ciliary body in the right eye of a 1-year-old goldfish (Carassius auratus) had spindle and epithelial cells arranged either in columns or around a central lumen. Vitreous-like material was found within the tumor. A medulloepithelioma is a most unusual tumor in fish in which ocular tumors are rare. © 1978, American College of Veterinary Pathologists.
