Dermatoscope image of pemphigus foliaceus lesions on the skin of a 51 year old Indian woman. Pemphigus is a general term for a group of blistering autoimmune diseases, where the immune system attacks the skin and mucous membranes.

Treatment for pemphigus conditions usually involves the use of high doses of steroids, with antibiotics to prevent infection of the blisters.
