Abstract

According to the size of nevus, a congenital pigmented nevus may be classified as small, medium, and giant. Among these, giant congenital pigmented nevus is known to have high potential for malignant transformation. The rate of malignant transformation is different according to lesional anatomical sites. We describ a case of a 48-year-old man who had a maignant melanoma arising from giant congenital pigmented nevus on the left thigh. Wide excision and inguinal lymph node dissection were performed but distant metastases were found four months later.
