Abstract

A 52 year-old Korean male with angioimmunoblastic lymphadenopathy(AILD) had generalized erythematous maculopapular eruptions with excoriation of the skin. The skin biopsies from two different sites revealed characteristic histologic features exhibiting nodular infiltrates around the skin appendages and blood vessels in the reticular dermis. The infiltrates consisted of many plasma cells. Plasmacytoid lymphocytes, immunoblast and histiocytes arranged in nodules of varying size. A small amount of amorphous eosinophilic material deposited within the cellular infiltrates with proliferation of arborizing capillaries. These histologic findings were similar to those noted on biopsy specimens of the involved lymph nodes. Cutaneous lesions of diverse histology associated with AILD were discussed on the basis of pathogenesis of AILD.
