I went to see a dermatologist because my doctor would not give me steroid pills for my rash on my leg as my previous doctor had done. It then spread up my leg, over my knees about 5 inches, the rash also is on my arms, and my abdomen down to my pubic bone. Today it looks like it is on the perimeter of my armpits and in the area of my groin and my breasts are also itching. The dermatologist gave my a prescription for steroids and I took them for 5 days, it appeared to help, but has returned. It had been treating it as eczema, but the dermatologist, took some skin for a biopsy, will not know the results for a week. He also mentioned it could be a kind of cancer but I cannot remember the name because it was a long name. can you make any guesses about what he may have mentioned. I am a 74 year old woman.
