We report a case of atypical urticaria associated with IgA multiple myeloma. A 79-year-old man presented with a two-month history of wheal-like erythema, which lasted approximately one week without any response to anti-histamines. Histological examination of a lesion revealed leukocytoclasia as well as perivascular leukocytic infiltration, being consistent with urticarial erythema. Laboratory investigation showed markedly elevated serum IgA concentration and M-protein in serum protein electrophoresis. A bone marrow examination led to a diagnosis of myeloma. An immunofluorescence study failed to detect any IgA deposit in the lesion. However, the wheal-like eruptions disappeared when the IgA myeloma was treated and reappeared when it relapsed. We conclude that this long lasting urticaria was the cutaneous manifestation of IgA myeloma.

A 70-year-old-male had suffered from non-pruritic, erythematous eruptions on the trunk for 3 months without any general symptoms. The individual lesions lasted for several days. Laboratory investigation showed marked elevation of serum immunoglobulin A (2235 mg/dL) with monoclonal gammopathy (IgA k-type). Monoclonal gammopathy of undetermined significance was diagnosed. Histopathological examination of the eruption revealed diffuse neutrophilic infiltration with leukocytoclasia in the dermis. There was no vasculitis. Treatment with antihistamines alone was not effective. Diaphenyl sulfone (DDS) at 75 mg/day dramatically improved the skin lesions. A similar case of urticarial erythema associated with IgA myeloma has been previously reported. We suggest that neutrophilic, urticaria-like erythema associated with IgA monoclonal gammopathy may be regarded as a new entity.

Cutis laxa (CL) is an inherited or acquired connective tissue disorder characterized clinically by loosely hanging skin folds. There is often preceding cutaneous inflammatory eruption (ie, urticaria, eczema, erythema multiforme), and there is frequently internal organ involvement of the gastrointestinal, urogenital, pulmonary, and cardiovascular systems. Histologically, there are degenerative changes in the dermal elastic fibers. Of the few reports on this rare disorder, authors have speculated about an immune-mediated destruction of elastic fibers, and monoclonal gammopathies, such as multiple myeloma or heavy chain deposition disease, have a recognized association with CL. We report an unusual case of rapidly progressing acquired CL associated with leukocytoclastic vasculitis, IgA myeloma, and an immune complex-mediated glomerulonephritis. Light microscopy of the lax skin revealed complete absence of elastic fibers in areas of vasculitis.
