Sertolioma in a Canine: Case Report

Abstract

Sertolioma is frequent in elderly, non-castrated and cryptorchid dogs, originating from leidig, sertoli and/or seminoma cells, benign and unilateral. The objective of this study was to report the case of a canine, male, 5 years old and cryptorchid, describing the changes caused by the myelotoxicity of hyperestrogenism secondary to sertolioma. The animal showed swelling in the abdominal region, genital hyperpigmentation, pendular foreskin, generalized gynecomastia and cryptorchidism. In the blood count, severe anemia, leukopenia and thrombocytopenia were found. On ultrasound, it was possible to identify a mass in the caudal abdominal region, with an ectopic left testicle and a reduced right testicle with degeneration. An exploratory laparotomy was performed to extract the ectopic left testicle, and orchiectomy of the right testicle, requiring blood transfusions during surgery and 7 days after hospital discharge. As treatment, the patient received analgesics (dipyrone and tramadol), antibiotics (Amoxicillin + Potassium Clavulanate) and Lithium therapy. The treatment with lithium and the surgical procedures were successful in this case, as the animal gained a survival with quality of life, following the treatment and performing periodic hemograms.
