Erythema migrans arciforme et palpabile

Abstract

A 39-year-old man presented with an annular clearly palpable erythema on the décolleté. Based on clinical and histopathological findings, palpable migratory arciform erythema was diagnosed. This skin condition is classified as a rare type of T-cell pseudolymphoma. It is still a matter of debate whether palpable migratory arciform erythema is a specific entity or a clinical variant of lymphocytic infiltration of the skin (Jessner-Kanof). Topical corticosteroids or oral antibiotics are generally used. In our patient, UV-A1 therapy led to a complete regression of the lesions.
