IgA and IgG/IgA intercellular dermatosis: a clinicopathological case series of 15 patients.

Clinicopathologic features of IgG/IgA pemphigus in comparison with classic (IgG) and IgA pemphigus. Pemphigus with IgA deposits, called intercellular IgA dermatosis (IAD)1 or IgA pemphigus,2 is rare. Some cases are associated with anti-desmocollin antibodies.3 Intermediate IgG and IgA forms were reported, called intercellular IgG/IgA dermatosis (IGAD)4 or IgG/IgA pemphigus.5 We conducted a clinical pathological study to compare IAD and IGAD.
