Resumen:
Epidemiological profile of dogs with skin tumors diagnosed at the Veterinary Hospital of the Federal University of Campina Grande. The main epidemiological aspects related to the cases of cutaneous neoplasias diagnosed in
the Laboratory of Animal Pathology of the Veterinary Hospital of the Federal University of
Campina Grande, Patos, Paraíba, are described. For this, a retrospective survey of necropsy
and biopsy protocols was performed, identifying all cases of skin tumors in dogs from 2003 to
2015. Information was then obtained regarding age, race, type of neoplasia, location and
sex. Of the 256 cases, 263 neoplasms were diagnosed, since some dogs had more than one
type of tumor. There were 21 types of neoplasms, in which 112/263 (42.59%) were of
epithelial origin, 74/263 (28.14%) had mesenchymal origin, 58/263 (22.05%) had melanocytic
e19 / 263 (7.22%) originating from round cells. In general dogs without defined breeds had
the highest number of cases. The age group had a predominance between nine and thirteen
years, 81/256 (31.64%). Regarding sex, males obtained the largest number149 / 256
(58.20%). According to the biological behavior the benign and malignant had the same
frequency 10/20 (50%). In descending order, the most common cutaneous tumors were
hemangiosarcoma 48/263 (18.25%), squamous cell carcinomas 43/263 (16.35%),
mastocytomas 31/263 (11.78%), trichoblastoma 16/263 (6.08%) and histiocytoma 14/263
