Abstract

According to the size of nevus, congenital nevomelanocytic nevi(CMN) could be divided as small, medium, and large or giant. Giant CMN is well known as precursor for malignant melanoma, but the risk of malignant transformation in small or medium-sized CMN is the subject of controversy. We report a case of 54-year-old man who was diagnosed as malignant melanoma arising medium -sized CMN on the trunk. Local wide excision was performed but distant metastases were found 5 year later.
