I have rashes that are located behind my neck, the palm of one hand, and the buttock area. (Attached is the buttock rash). They are extremely pruritic, chronic, and flare up frequently. Often dry scaly skin detaches from the area with subsequent bleeding from the underlying skin. The skin is also darker in pigmentation. Can you give me a diagnosis (ezcema?, psoriasis?, ???) and help with suggestions for topical treatment?
