Abstract

Some canine typical Sertoli cell tumors (SCT) induce signs of hyperestrinism. However, whether variant lipid-rich SCTs have signs of hyperestrinism remains largely unknown. In the present study, an 11-year-old male Pekingese dog showed significantly elevated serum estrogen and characteristic signs of hyperestrinism such as gynecomastia and alopecia. Cytological, radiological and ultrasound examinations found testicular mass, prostatitis with squamous metaplasia, and cystitis. Pathologically, the tumor lesions consisted mainly of lipid-rich tumor cells with signet-ring appearance, which were immunohistochemically positive for vimentin and anti-$M{\ddot{u}}llerian$ hormone. Based on the findings, a diagnosis of lipid-rich Sertoli cell tumor was established. In conclusion, a canine lipid-rich SCT induced signs of hyperestrinism and caused prostatitis via squamous metaplasia due to its excessive secretion of estrogen.
