IgA pemphigus

IgA pemphigus is a subtype of pemphigus with two distinct forms:

• Subcorneal pustular dermatosis (also known as Sneddon–Wilkinson disease and pustulosis subcornealis) is skin condition that is a rare, chronic, recurrent, pustular eruption characterized histopathologically by subcorneal pustules that contain abundant neutrophils. This is distinct from and not to be confused with subcorneal pustular dermatosis type of IgA pemphigus. Sneddon's syndrome, also known as Ehrmann-Sneddon syndrome, is also a different syndrome.
• Intraepidermal neutrophilic IgA dermatosis is characterized histologically by intraepidermal bullae with neutrophils, some eosinophils, and acantholysis.

History

Early descriptions were made by Darrell Wilkinson, a British dermatologist.
