IgA pemphigus is a subtype ofpemphigus with two distinct forms:

• Subcorneal pustular dermatosis (also known as Sneddon–Wilkinson disease and pustulosis subcornealis)^[1] is skin condition that is a rare, chronic, recurrent, pustular eruption characterized histopathologically by subcorneal pustules that contain abundant neutrophils.^{[2][3]: 203} This is distinct from and not to be confused withsubcorneal pustular dermatosis type of IgA pemphigus.Sneddon's syndrome, also known as Ehrmann-Sneddon syndrome, is also a different syndrome.^[4]
• Intraepidermal neutrophilic IgA dermatosis is characterizedhistologically byintraepidermalbullae withneutrophils, someeosinophils, andacantholysis.^[3]: 465

Early descriptions were made byDarrell Wilkinson, a British dermatologist.^[5]
