Dear Doctor Im About 37 Years Old. My Scrotum Skin

Dear doctor
Im about 37 years old. My scrotum skin has become very thick, dark and very deeply wrinkled. It itches a lot and when i scratch a fine grey dust falls off. The skin feels sore from the itching. When i towel myself after a bath, it leaves a brown smelly stain on the towel. Ive tried to show dermatologists this condition, but they issue prescriptions on verbal descriptions and show no interest in wanting to examining the condition. Can i send u some photos for you to understand the condition better. Ive had this condition for several years now and want ti have this treated so my scrotum can look normal. Can ualso recommend a good dermatologist in delhi who i can consult with. Thank you.
