Needs assessment for general dermatologic surgery.

This article reviews current recommendations, strength of evidence, and areas in need of further research in the surgical treatment of melanoma and nonmelanoma skin cancers, as well as other select cutaneous neoplasms. Cryosurgery, electrosurgery, photodynamic therapy, and surgical excision are discussed. Local anesthesia, suturing technique, postsurgical dressings, and optimization of scarring are briefly reviewed. In general, large, high-quality, randomized controlled trials on which to base recommendations are lacking.
