Erythema elevatum diutinum.

First described by Hutchinson in 1878, erythema elevatum diutinum (EED) is a rare disease characterized by persistent red, raised nodules and plaques in a symmetrical, acral distribution. The disease occurs equally in the sexes, primarily in the 30- to 60-year age group. We report a representative case of EED which responded to current agents, and briefly review the status of the disease.
