Hi, my dog has enlarged inguinal testical and showed hyperpigmentation and symmetrical hair loss. May I know will the skin issue resolved after castration if the skin issue is caused by the effect of hormonal changes due to testicular tumor? Thanks!

Some skin problems are caused by sex hormones, and may resolve after castration. Some skin issues are unrelated. It will be a matter of having the surgery and seeing if the skin problems resolve. I hope that all goes well for Miley.

My pitbull formed an oreo size sertoli cell tumor on his testicle and I wanted to know how painful he's in any pain? He seems fine and he eats so much and he's still very active for a 10 yr old doggie. I want to take him in to see a Vet Doctor but they are closed. What type of temporary relief medication can I give him?

Thank you for your email. Without seeing Pacman, I can't recommend any treatment for the lesion that you are worried about. If he is eating and drinking, not bothering with the lesion, and seems fine otherwise, he should be fine until you can get him in to see a veterinarian. It is Friday, and most veterinary clinics are open today - if your clinic is closed, they should have an after-hours contact if you feel that he really needs to be seen. I hope that everything goes well for him.

Our 13 yr old Lab has been diagnosed with Sertoli Tumor, and advised us to have him castrated. He's in reasonably good health for his age, (except arthritis and some joint stiffness) and seems to have a little dementia. We are afraid the surgery might be too much for him. The question is, what if we don't do the surgery? At his age will it make a difference?

There is an increased risk of complications when older dogs are anaesthetised; but with modern anaesthetics and pre surgery blood test, these risks may be mitigated. The tumour is locally invasive and may cause feminisation. The choice to operate is yours, but I would recommend it. Regards Dr Callum Turner DVM
