Abstract
Background: Erythema elevatum diutinum (EED) is a rare, chronic form of cutaneous vasculitis that can result in fibrosis. Four patients infected with the human immunodeficiency virus (HIV) had unusual nodular lesions of EED. Objective: Our purpose was to document the occurrence of these lesions in HIV-infected patients and to characterize the histopathologic and immunophenotypic features of nodular EED. Methods: Clinicopathologic studies were supplemented by special stains of biopsy specimens. Results: EED may be a complication of HIV infection. Nodules of EED are composed of small aggregates of Mac-387+ spindled cells. Within the aggregates can be seen neutrophils, nuclear dust, and fibrin. The marked fibrosis of the lesions may account for the lack of response to dapsone. Conclusion: EED should be considered in the differential diagnosis of juxtaarticular nodules in HIV-infected patients; its diagnosis can be confirmed by biopsy.
