Erythema elevatum diutinum is indeed a rare disease. Clinicians of wide experience may deny any acquaintance with the disorder, while standard textbooks of dermatology usually dispense with the subject in a short paragraph of small print. During the past 25 years case reports or dissertations on erythema elevatum diutinum appearing in the world's medical literature have averaged less than one a year.1,2 Erythema elevatum diutinum's entity claim has been repeatedly challenged. Its place in classification remains unsettled, and differences of opinion exist regarding its pathogenesis and histopathologic interpretation. These issues are acknowledged but purposely avoided, the sole intent being to record an example of this unusual condition.
