Highlights & Basics
- Pemphigus encompasses a group of potentially life-threatening autoimmune bullous diseases characterized by blisters and erosions of the mucous membranes and skin.
- Pemphigus vulgaris (PV) is the most common variant and affects skin and mucosa.
- Pemphigus foliaceus (PF) is confined to the skin. Paraneoplastic pemphigus (PNP) is rare; it can involve the skin and mucosal surfaces of the eyes, mouth, nasopharynx, and esophagus.
- Diagnosis is based on clinical findings of erosions (epidermal loss) and blisters of the skin, mucosa, or both.
- Direct immunofluorescence staining of biopsied skin shows immunoglobulin and C3 deposits on the keratinocyte surface, and histology reveals keratinocyte acantholysis.
