The nosologic position of erythema elevatum diutinum (persistent elevated erythema) is still uncertain. Over ten years ago Weidman and Besancon1 made an admirable attempt to prove its identity, isolating an organism (Streptococcus ignavus) and divorcing the condition from granuloma annulare and the erythema multiforme perstans group of cutaneous diseases. Crocker and Williams,2 Trimble3 and Gray4 also considered it a separate entity. Trimble and Weidman and Besancon felt sympathetic to the hypothesis that the so-called Bury type and granuloma annulare were the same but nevertheless recognized the Hutchinson type as existing separate and distinct from granuloma annulare.
We agree with Weidman and Besancon that the sparsity of cases appearing in the literature has made it impossible to collect sufficient data to determine the clinical and histologic requisites for diagnosis of this rare disease.
