Erythema elevatum diutinum in a patient with well-controlled Crohn disease.

Erythema elevatum diutinum is a rare, chronic cutaneous leukocytoclastic vasculitis, with prominent fibrosis at its later stage. In this article, we report a case of erythema elevatum diutinum in a 23-year-old woman with well-controlled Crohn disease. To our knowledge, erythema elevatum diutinum has been reported in only three other cases of Crohn disease, in which eruptions of erythema elevatum diutinum were associated with features of active Crohn. Our patient was in clinical remission at the time of erythema elevatum diutinum onset, making this report significant not only for its uncommon presentation, but more importantly, to aid readers. diagnosis and clinical management of similar cases.
