Angioimmunoblastic lymphadenopathy with scleromyxedema-like lesions and serum monoclonal protein.

A patient was followed up for 5 yr for an illness diagnosed histologically as angioimmunoblastic lymphadenopathy. His serum contained a monoclonal protein of the IgM type, and biopsies from papular skin lesions revealed scleromyxedema-like features. The unusual association of this kind of cutaneous lesion with angioimmunoblastic lymphadenopathy and a monoclonal IgM is discussed.
