We present the case 66-year-old male, poorly controlled diabetic peripheral arterial disease, obesity, hypertension, Cushing's syndrome disease requiring hemodialysis who develops an acquired dermatosis.

OBJECTIVE To examine the frequency of antidesmoglein 1 (Dsg1) and antidesmoglein 3 (Dsg3) IgA autoantibodies in IgA pemphigus. DESIGN We developed an enzyme-linked immunosorbent assay against recombinant Dsg1 and Dsg3 to detect IgA autoantibodies. PATIENTS Twenty-two patients with IgA pemphigus were studied. Among them, 10 patients had subcorneal pustular dermatosis type, 9 patients had int...

BACKGROUND Linear IgA bullous dermatosis is an autoimmune blistering disease characterized clinically by the presence of small tense blisters and immunologically by the presence of IgA at the dermal-epidermal junction.
