Paraneoplastic epidermolysis bullosa acquisita associated with multiple myeloma.

Epidermolysis bullosa acquisita is a rare acquired autoimmune subepidermal blistering disease that clinically resembles other vesiculobullous lesions such as pemphigus vulgaris and cicatricial pemphigoid. Multiple myeloma is the most common plasma cell malignant disorder characterized by a single clonal expansion and increased level of a single immunoglobulin. Epidermolysis bullosa acquisita has been reported with other systemic diseases such as lymphoma.
