Sarcoma histiocítico conjuntival em um felino

Abstract

We report an unpublishedclinical case of a histiocytic sarcoma located in the conjunctiva of the third eyelid with invasion of the bulbar conjunctiva, extraocular muscle and orbit bone in the right eye of a seven year old, mixed-breed, male cat, assisted at the Veterinary Ophthalmology Sector of the Veterinary Hospital of the assisted at the Veterinary Ophthalmology Sector of the Veterinary Hospital of the Center of Agrarian Sciences of the Federal University of Paraíba (CCA-UFPB) Histiocytic sarcoma is a round cell tumor, defined individually or in small quantities, and demonstrating locally invasive growth. They are common in dogs and rare in cats. Few descriptions of histiocytic sarcomas diagnosed in cats affected multiple organs, however there was no previous description in cat eye tissues. The diagnosis was based on cytological and histopathological exams. Exenteration with subsequent filling of the orbit with acrylic resin was the chosen treatment for allowing complete surgical resection of the tumor with a wide safety margin.
