To the Editor.—  Linear IgA bullous dermatosis is a vesiculobullous eruption characterized by linear deposits of IgA along the basement membrane zone that are seen by using direct immunofluorescence methods.1 We report an unusual case of linear IgA bullous dermatosis with dermatomyositis developing soon thereafter.

Report of a Case.—  In January 1990, an erythematous scaly eruption on the trunk and extensor surfaces developed in a 56-year-old white woman. Four months later, bullae developed on her lower extremities, whereupon she was referred to the dermatology service.Findings from her physical examination revealed a patchy erythematous scaly eruption on her face, trunk, and extensor surfaces and several 4- to 5-mm tense bullae on her lower extremities. Laboratory studies showed the following normal or negative findings: complete blood cell count with platelets, chemistry profile, urinalysis, erythrocyte sedimentation rate, creatinine phosphokinase, total complement level, antinuclear antibody, and rheumatoid factor. The biopsy specimen of a bullous lesion revealed a subepidermal blister
