The challenge for the physician is to distinguish cutaneous melanomas, which account for the overwhelming majority of deaths resulting from skin cancer, from the remainder, which are usually benign. Cutaneous melanoma can occur in adults of all ages, even young individuals, and people of all colors; its location on the skin and its distinct clinical features often permit detection at a time when complete surgical excision leads to cure. Examples of malignant and benign pigmented lesions are shown in Fig. 72-1.
