The clinical and histologic features of cutaneous histoplasmosis in three patients with acquired immunodeficiency syndrome (AIDS) are described. The patients presented with multiple discrete papules on the extremities, trunk, and face, some of which were follicular. Histologically, the skin biopsies were characterized by a sparse perivascular infiltrate with polymorphonuclear leukocytes, lymphocytes, and occasional histiocytes. Prominent leukocytoclasia and associated dermal necrosis were seen around the superficial blood vessels of the dermis. The Histoplasma capsulatum organisms were for the most part extracellular and difficult to visualize on the hematoxylin and eosin-stained sections. A diagnosis of atypical leukocytoclastic vasculitis was considered. Histoplasmosis is a relatively common mycosis among AIDS patients, and it is sometimes the first manifestation of the syndrome. The clinical and histologic findings described herein may be relatively common among AIDS patients and are quite different from those of classic disseminated histoplasmosis.
