This case report describes bilateral cryptorchidism in a 9.65kg, 5-year-old American Eskimo male dog presented at the clinic. The dog showed clinical signs such as dullness, anorexia, jaundice, dyspnoea, and pedal oedema of the right hind limb with the absence of both testicles in the scrotal sac. The stud dog had bilateral swelling at the inguinal region, which was more pronounced on the right than the left. Abdominal ultrasound scan showed both right and left testicles to be solid masses, but the right testicle had increased echogenicity while the left had mixed echogenicity with anechoic center suspected to be inflammatory fluid. The cryptorchid testicular masses were markedly enlarged, with the left and right testicular masses measuring 8.5cm and 16.2cm in diameter respectively. Histopathology of testicular tissue samples confirmed Sertoli cell tumour. Hormonal assay also showed elevated estrogen levels and reduced testosterone levels. In addition, metastasis to both kidneys was found. Due to late presentation, the dog died despite intensive care and management. Pet owners must be enlightened on the presentation and diagnosis in order to prevent poor outcomes. Early detection and diagnosis of cryptorchidism is crucial to the reproductive health of a pet and the retained testicles should be removed to prevent cancer development.
