Neoplasias testiculares en caninos: Un caso de tumor de células de sertoli

Abstract

Testicular neoplasms are not common in domestic animals. Among domestic animals, canines manifest them with more frequency (0.7% to 4.6% of all canine tumors). Some predisposing factors including age and the presence of criptorquidia uni or mainly bilateral have been identified. Testicular neoplasms more frequent are Sertoli cell tumor, the Leydig cell tumor and seminomas, which generally present as benign. Following clinical evaluation the recommended treatment is bilateral orchiectomy, including in cases involving Cryptorchidism. In the first part, this work presents a revision of the topic; in the second part it describes a Sertoli cell tumor case in a Cocker dog that presents with a retained testicle and testicular feminization syndrome. In this case histopathological diagnosis was made after surgical removal of the abdominal mass and extirpation of the testicle retained in the scrotum.
