Resumo

Background: In dogs, abdominal testes have higher risk of malignant transformation, and the Sertoli cell tumor is the most common type of testicular cancer in the species. This neoplasia can lead to an increase on estrogen production, causing a paraneoplastic feminization syndrome with dermatologic, behavioral and blood repercussions. When located inside the abdomen, the Sertoli cell tumor can compress adjacent organs, worsening the prognosis. Thus, this study aimed to report a case of an intra-abdominal Sertoli cell tumor in a dog associated to multiple organic complications.Case: A 4-year-old male Shih-tzu was admitted at the Veterinary Hospital of Universidade Federal Rural do Semi-Árido (UFERSA), with a history of abdominal cryptorchidism and the development of dermatological signs, such as alopecia and hyperpigmentation, with an evolution of two months. At physical examination it was observed alopecia on lumbosacral region and on hind limbs, hyperpigmentation, gynecomastia and pendulous prepuce, suggestive of feminization syndrome. A firm mass was palpated on caudal abdomen. The following exams were requested: complete blood cell count, serum biochemistry (alanine aminotransferase, alkaline phosphatase, creatinine and urea), abdominal ultrasonography and fine needle aspiration cytology of the abdominal mass. Hematological and biochemistry profile were within the normal range for the species. On the ultrasonography, regular and rounded structures were observed, suggesting ectopic testes (left testis: 2.37 x 2.95 cm; right testis: 1.92 x 1.38 cm). The left testis presented characteristics of malignant transformation. The cytology of the abdominal mass suggested Sertoli cell tumor. The dog was submitted to an exploratory laparotomy. The right testis was atrophied and its orchiectomy was performed.[...](AU)
