Pemphigus foliaceous (PF) one of the major clinical variants of pemphigus, is characterized by superficial blisters and anti-epidermal autoantibodies. The epidermal antigen with which PF autoantibodies react is a desmosomal protein designated desmoglein 1 (dsg1). There are two forms of PF-a sporadic form which has worldwide distribution, and an endemic form, which has only been observed in certain rural areas of Brazil, Columbia and Tunisia.
