SEX HORMONE DERMATOSES DUE TO SERTOLI CELL TUMOR ASSOCIATED WITH FEMINIZING SYNDROME IN A CRYPTORCHID DOG

A nine year old male Golden retriever was presented to the Small Animal Dermatology outpatient unit of Madras Veterinary College Teaching Hospital with a history of symmetrical alopecia, enlarged pendulous prepuce and haematuria. Detailed clinical examination revealed cryptorchid, gynecomastia, pendulous preputial sheath and alopecia originating in the lumbar region. The entire coat was dull, dry and epilated easily. Resting telogen phase was also observed in trichogram. Trans abdominal palpation showed an enlarged solid mass in the right inguinal region. Radiography and abdominal ultrasonography revealed the presence of neoplastic retained right testicle. Haematology revealed leucocytosis, while serum biochemistry remained within the normal reference range. Histological examination confirmed the presence of sertoli cell tumors that were primarily responsible for the feminizing syndrome. Under general anaesthesia, caudal ceilotomy was done and retained testicles were identified. Testicular tumor with torsion was ligated with PGA 1-0 and excised, similarly the other normal testicle was also removed. Broad spectrum antibiotics and supportive therapy were also administered for 5 days. Complete remission of all clinical symptoms occurred within 3 months post orchiectomy.
