Hi,
Pemphigus is an autoimmune disease of the skin and mucous membranes that causes vesicles (blisters), bullae and raw sores. It may be triggered by medications, such as penicillamine.
Pemphigus Foliaceus is the least severe of the three varieties. Desmoglein 1, the protein that is destroyed by the autoantibody, is only found in the top dry layer of the skin. Pemphigus foliaceus (PF) is characterized by crusty sores that often begin on the scalp, and may move to the chest, back, and face. Mouth sores do not occur. It is not as painful as pemphigus vulgaris, and is often mis-diagnosed as dermatitis or eczema.
The most common treatment is the administration of oral steroids, especially prednisone. This form is not associated with cancer.
If skin lesions do become infected, antibiotic may be prescribed. In addition, talcum powder is helpful to prevent oozing sores from adhering to bedsheets and clothes.

It si an auto-immune disorder, so it may keep coming on and off, also it is not contagious.
