NEOPLASIAS CUTÂNEAS DE ORIGEM SEBÁCEA DIAGNOSTICADAS EM CÃES NA REGIÃO METROPOLITANA DE JOÃO PESSOA – PB

Abstract

This work aimed to perform an anatomopathological study, emphasizing the clinical, epidemiological and morphological aspects of sebaceous cutaneous neoplasms diagnosed in dogs in the metropolitan region of João Pessoa, Paraíba. The samples were obtained from excisional biopsies of dogs treated at veterinary clinics in the metropolitan area of João Pessoa - PB. Epidemiological information was recorded in specific records. After the samples were collected, they were packed in 10% formalin, serially cut, then routinely processed into paraffin blocks, cut 4 to 5 μm thick, to make slides, followed by staining with HE. Seven dogs had defined breed 87.50% (7/8) and one undefined breed 12.50% (1/8). The races were Poodle with five 62.50% (5/8), Shi Itzu, Beagle and mixed breed each with 12.50% (1/8). As for sex 87.50% (7/8) were females and 12.50% (1/8) were male. The mean age of the affected dogs was 9.12 years old. The clinical presentation in all cases wereexophytic nodules. The diagnosis of sebaceous cutaneous neoplasms was three sebaceous adenomas: 37,50% (3/8), three sebaceous carcinomas 37,50 (3/8), sebaceous epithelioma 12,50% (1/8), and meibomian carcinoma 12, 50% (1/8). This study concludes that cutaneous neoplasms of sebaceous origin were the most frequent in the study region. Observing a higher occurrence of adenomas and carcinoma of the sebaceous gland, followed by sebaceous epithelioma and carcinoma of the Meibom gland. The poodle breed was the most affected.
