Pemphigus foliaceus: A rare blistering skin lesion

Abstract

Pemphigus foliaceus is a benign variety of pemphigus group. It is a rare autoimmune blistering disease that affects the skin without mucosal involvement. It can present in endemic and sporadic form; whereby endemic form is common in Brazil and Tunisia, known as fogo selvagem. There was no previous case reported in Malaysia. We report a case of a 43-year-old man, who presented with generalized extensive blisters and vesicles that form crust and scale. The full evaluation established the diagnosis of pemphigus foliaceous. Delay in diagnosis can lead to poor outcomes. Primary care practitioners should be aware of this since the condition can mimic eczema, specifically photodermatitis.
