RT Journal Article SR Electronic T1 Adult linear IgA disease associated with an erythema multiforme-like drug reaction JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 445 OP 450 VO 54 IS 5 A1 Argenyi, Zsolt B.

YR 1987 UL http://www.ccjm.org/content/54/5/445.abstract AB The authors describe a 58-year-old woman who experienced an erythema multiforme-like reaction following therapy with cefamandole naftate. Histologically, findings were consistent with erythema multiforme, but diffuse linear deposition of IgA was demonstrated at the dermo-epidermal junction by direct immunofluorescence. Ultrastructurally, deposits were located beneath the basal lamina, around the anchoring fibrils. These observations illustrate that adult linear IgA bullous dermatosis can mimic the clinical and histological features of erythema multiforme and suggest the possibility of drug-induced pathogenesis.
