Epidermolysis bullosa acquisita and multiple myeloma.

The coexistence in the same patient of epidermolysis bullosa acquisita (a rare, autoimmune, acquired mucocutaneous blistering disorder) and multiple myeloma (a plasma cell neoplasm) is extremely uncommon. We describe a patient in whom both of these diseases occurred simultaneously. Intravenous immunoglobulins were used to treat both diseases.
