Erythema elevatum diutinum with extensive acro-osteolysis.

Erythema elevatum diutinum (EED) is a rare chronic skin disease with cutaneous vasculitis, characterized by the absence of systemic vasculopathy. We describe a 79-year-old white woman who has been followed with the diagnosis of EED for 27 years. Our patient has a previously unreported combination of EED and acro-osteolysis. After reviewing possible reasons for the association, her vasculitis seems the most likely factor.
