복합 모반 주위에 발생한 Halo Dermatitis 1예

Abstract

Halo dermatitis was first described as a halo-shaped eczematous change around a nevocellular nevus. However, other cases developed around various kinds of lesions including seborrheic keratosis or lentigo were reported later on, so it is now considered not to be specific for melanocytes or nevus cells. It has never been reported to be associated with regression of central lesion, in contrast to halo nevus. We report a case of halo dermatitis developed around a compound nevus in a 20-year-old male patient. On histopathologic examination, the central lesion was a compound nevus and the surrounding lesion was consistent with chronic eczematous dermatitis.
