My husband is 73 yrs. old and a diabetic. He developed a rash 5 weeks ago. He was seen by a MD and placed in a steroid. He was ref. to a Dermatologist and was seen today. They are unsure what this could be . The doctor obtained a biopsy today. The rash is on his neck, back, arms, chest, thighs, and buttocks. It does not itch,burn. No swelling or fever and he does not feel bad. I am concerned about him. I was a nurse for 41 years and I have never seen a rash like this.
