OBJETIVO: Analisar os aspectos clínicos e radiográficos em pacientes com diagnóstico de tumor de células gigantes ósseo, confirmado por histopatologia. MATERIAIS E MÉTODOS: Os dados clínicos e radiológicos (quando disponíveis) de 115 pacientes com diagnóstico de tumor de células gigantes ósseo foram analisados no presente estudo. RESULTADOS: Dos casos avaliados, 57,4% (66) eram do sexo feminino e 80% (92) eram da raça branca. A média de idade dos pacientes foi de 30 anos e a topografia mais freqüente das lesões foi a metáfise distal do fêmur, em 22,6% (26) dos casos. O aspecto radiográfico mais comum foi o de lesão puramente lítica, em 63,7% (51) dos casos. CONCLUSÃO: O tumor de células gigantes é uma neoplasia óssea relativamente comum, com predomínio em indivíduos da raça branca e com aspecto radiológico bem definido.
The present study aimed to describe the occurrence and epidemiological features of skin neoplasms diagnosed in dogs in the metropolitan region of Goiânia, Goiás state, Brazil. Diagnoses from dog biopsies from 2011 to 2016 provided by a private veterinary pathology laboratory were analyzed. The main diagnoses were mast cell tumor, hemangiosarcoma, squamous cell carcinoma, malignant melanoma, and hemangioma. Highest frequency of neoplasms was found in female dogs, dogs aged >8 years, and purebred dogs, particularly the American Pit Bull Terriers and the Poodles. Most common sites affected by the neoplasms were the limb and the head. Using multiple correspondence analysis, groups of neoplasms were found to be associated with different epidemiological features and the size of the neoplasms was associated with the biological behavior. The results of this study described predispositions and verified the importance of different types of skin neoplasms in dogs in the region being studied.
