TUMOR DAS CÉLULAS DE LEYDIG EM UM EQUINO CRIPTORQUIDA - RELATO DE CASO

Abstract

Neoplasms of Leydig cells or Leydigocitoma are quite uncommon amongst equines, in general, testicular neoplasms are infrequent among equine, being often observed in other species, such as dogs and bulls. They are benign neoplasms, with low metastatic power and because they present nonspecific clinical signs are accidentally diagnosed. Histopathological examination is the most efficient means of diagnosis in the confirmation of this neoplasm. The present work aims to describe a case of Leydig Cell Tumor diagnosed in the testicular region of an equine, attended at the Veterinary Hospital of the Federal University of Paraíba, located in Areia - PB. The equine, male, Quarter Horse breed, six years ild, went through a clinical evaluation, followed by a diagnosis of cryptorchidism. A clinical evaluation was performed, although the parameters are within the normal range for the species. Complementary exams were requested, including transrectal and transabdominal ultrasonography for visiualisation of the retained testicle in the cavity and testicular architecture and hematological analysis as a pre-surgical evaluation. The recomended treatment was orchiectomy, aiming the removal of the retained testicle. After the procedure, the surgically removed testicle was sent to the Laboratory of Veterinary Pathology (LVP), for hiystopathologial evaluation, with diagnosis of neoplasm of Leydig Cells or interstitial cells. After the surgical recovery period, the animal could return to its activity, without incurrences or interferences to its performance,
