Tumores testiculares em cães necropsiados pelo sedivet-lpv/UFSM durante os anos de 2019 a 2021

Abstract

Reproductive system tumors are the third most frequent type of neoplasms, behind only skin and breast tumors, with testicular neoplasms commonly occurring in dogs, affecting about 10% of this population. Primary testicular tumors arise from the specialized cells that make up the organ, and include the germline germline cell tumor (seminoma), Sertoli cell tumor (sertolioma), and Leydig interstitial cell tumor (leydigoma) , being able to present age and racial predispositions. This study aimed to describe the testicular neoplasms found in necropsied dogs between the years 2019 and 2021, by the Veterinary Diagnostic Consulting Service (SediVet / LPV-UFSM), in order to characterize the morphological aspects of the lesions and their forms of occurrence and consequences, and suggest their prevalence in the study. Thus, it was observed during the period evaluated that testicular neoplasms had a low prevalence (11.5%) among necropsied dogs, being an incidental finding unrelated to the cause of death, affecting mostly elderly and geriatric individuals (75%), there is no relationship with the race. Testicular tumors occurred mostly unilaterally (70.8%), and there may be an association between tumors in the same testicle or between the testicles, which in turn may appear concomitantly with other lesions, with prostatic hyperplasia being the most observed associated finding.
