Acquired cutis laxa associated with multiple myeloma.

Cutis laxa is an uncommon condition characterized by loose and redundant skin. Biopsy results are positive for a reduction in or an absence of elastic fibers in the dermis. Cutis laxa is acquired or congenital. The acquired form is either a generalized insidious form (type I) or a form associated with prior inflammation (type II). Cardiovascular, pulmonary, gastrointestinal, and urologic complications may occur. In the past, cutis laxa was associated with plasma cell dyscrasia. We report on a characteristic cause of cutis laxa to alert clinicians to this uncommon manifestation of multiple myeloma.
