Frequência de neoplasias cutâneas em cães atendidos no hospital veterinário da universidade federal de uberlândia durante os anos 2000 a 2010

Abstract

We analyzed the archives of the Animal Pathology Laboratory of the Federal University of Uberlândia Veterinary Hospital from 2000 to 2010 with the aim of conducting an epidemiological study. Protocols for skin biopsies of dogs were selected and the following information was collected: morphological diagnosis, anatomical location, age, gender, and breed. Five hundred forty-nine skin tumors were diagnosed in 543 dogs, of which 281 were males and 247 were females. Adult and older dogs were the most affected, and mongrel dogs, Poodles, Boxers, Pit Bulls, and Dashchunds were the most frequent breeds. Malignant tumors were present in 65.39% dogs, and most tumors were derived from epithelial cells. Squamous cell carcinoma was the predominant neoplasia, followed by mast cell tumors and histiocytoma. With respect to the anatomic location, the abdomen (19.49%), head (16.40%), and limbs (15.30%) were the most frequently affected. Gender did not influence the probability of having a cutaneous tumor. With regard to tumor type, the canine population was more susceptible to squamous and mast cell tumors than to other skin tumors.
