악성 흑색종 양상의 위성병변을 보인 보통 청색모반 1예

Abstract

Malignant blue nevus is very rare, but it may represent a variant of malignant melanoma arising in a previously benign cellular blue nevus. It is most commonly found on the scalp of elderly mean, with recent changes, such as loss of the poorly defined border and the development of satellitosis. All of these features were present in our case. However, no malignant change was observed histopathologically. Only a few blue nevus with satellitosis has previously been reported as a benign lesion.
