Sertolioma em um canino associado à criptorquidia

Abstract

The sertolioma is one of the tumors that most affect older dogs, more incidents in criptorquidas animals. Usually these tumors are extremely expansive and can compress and destroy adjacent tissues. For their identification is necessary to carry out histopathological examination. This study aimed to report the occurrence of gonadopatia right criptorquidica, accompanied by neoplastic process associated in a dog of 10 years old. After orchiectomy the testes were sent to the Animal Pathology Laboratory of the Federal Rural University of Amazonia, and histopathological analysis the material was processed routinely for paraffin embedding and staining with hematoxylin -eosin (HE) and Masson's Gomory. Histologically, there was albugíneo by thickening of connective tissue proliferation. In the testicular parenchyma the tubules had only Sertoli cells were decreased in number and spaced proliferated dense connective tissue. The neoplastic process was located in a more central and, morphologically, it was observed in the tubular configuration, cell showing cytoplasmic vacuolization and some places featuring in palisades, characteristic morphological aspects of sertolioma.

“…Os sertoliomas, seminomas e leydigocitomas costumam apresentar um comportamento benigno (FARIA et al, 2018). A taxa de malignidade pode variar de 10 a 20% nas neoplasias das células de Sertoli, 5 a 10% nos seminomas e rareando nas neoplasias das células intersticiais (ALBERS et al, 2009).…”
