Pemphigus foliaceus (PF) is a chronic, benign, acquired autoimmune blistering disease characterized by fragile, superficial blisters and bullae.1 2 3 Patients commonly report blister formation on the skin, followed by localized lesions that typically begin on the trunk, face, or scalp.2 PF is a rare disease with a very low worldwide incidence and prevalence. However, it has a high incidence in endemic areas located in North Africa, Brazil, Colombia, and Peru.2 3 4 The disease affects both sexes equally, with symptoms typically appearing between the ages of 50 and 60 years.2 4 The universal type of PF that occurs sporadically is idiopathic, while the endemic type is linked exclusively to geographically-related environmental factors.
