Eosinophilic annular erythema in adults: report of two cases and review of the literature.

We herein report two cases of eosinophilic annular erythema in adults, which is rare. In both patients, lesions developed rapidly in few days and were located mainly on the trunk, buttocks, and extremities. Diagnosis was histopathological, with typical features including acute dermal inflammatory infiltrate with abundant eosinophils. One of the patients recurred after treatment on three occasions and finally cured spontaneously. The second patient recurred once and was then successfully treated with topical clobetasol. Clinical and histopathological features of eosinophilic annular erythema in adults have rarely been reported. A review of the literature and discussion of relationship with Wells syndrome are also included.
