Description
Summary:	ABSTRACT A dermoid is the presence of normal skin in an abnormal place. A mixed-breed, male, 4-month-old cat was presented with a history of ocular discomfort in the right eye. Ophthalmic examination on the right eye revealed lacrimation, blepharospasm, ocular discomfort and mild conjunctival hyperaemia. A mass with hair with a diameter of 5 mm on the temporal part of the bulbar conjunctiva was observed. Surgical excision of the mass was recommended. Histopathology of the excised tissue confirmed the diagnosis of a dermoid. There was no evidence of lesion recurrence 12 months after surgery. In the present case, complete surgical excision of the dermoid was curative. Although rare, dermoid should be included in the differential diagnosis of conjunctival disorders in cats. RESUMO Dermoide é a presença de pele normal em local inadequado. Um gato, sem raça definida, macho, com quatro meses de idade, apresentou histórico de desconforto ocular no olho direito. O exame oftálmico do olho direito revelou lacrimejamento, blefarospasmo, desconforto ocular e hiperemia conjuntival. Observou-se uma massa com pelos de 5mm de diâmetro na parte temporal da conjuntiva bulbar. A excisão cirúrgica da massa foi recomendada. A histopatologia do tecido excisado confirmou o diagnóstico de dermoide. Não houve recidiva da lesão 12 meses após a cirurgia. No presente caso, a excisão cirúrgica completa do dermoide foi curativa. Embora raros, os dermoides devem ser incluídos no diagnóstico diferencial de afecções conjuntivais em gatos.
