Current surgical management of skin cancer in dermatology

Skin cancer has become a major public health problem in the United States and worldwide. Epidemiologic studies confirm a continued increase in the number of basal cell carcinomas, squamous cell carcinomas, and malignant melanomas. Dermatologists, the primary caretakers of the skin, manage skin cancer with various modalities that have been time tested and found reliable, including excision, electrosurgery, cryosurgery, and Mohs micrographic surgery. Extirpative procedures for basal cell carcinoma and squamous cell carcinoma are considered with attention to cure, restoration of function, and cosmesis--in that order. The dermatologic management of melanoma is critical because early diagnosis and treatment of thin lesions has been the only effective improvement in melanoma management in the last several decades. Wide excision, with a 1-3-cm margin, of thin stage I melanoma has moved surgical management from the operating room to the outpatient surgical setting. Management of these increasingly common problems, as reviewed here, is principally responsible for the growth of surgical practice as a subspecialty of dermatology.
