The preoperative assessment of infiltration depth in melanoma and non-melanoma skin cancer by means of high-frequency ultrasound (≥18 MhZ) is essential for optimizing the therapeutic approach in our patients. Often, histologically confirmed skin tumors are directly referred to surgical departments for resection, and sonography is increasingly helping us identify those subjects who are no longer candidates for extensive surgical interventions. In cases of deep tumor infiltration, with potential surgical failure e.g. impairment of the quality of life and significant esthetic and functional complications, preoperative sonography can guide the surgeon to withstand from an operation and decide instead in favor of less mutilating radiooncological or medical treatment options. Furthermore, in melanoma patients, the preoperative knowledge of the tumor depth is essential for the determination of the therapeutic approach, the correct safety margins and the need of a sentinelnode biopsy. We herein encourage the use of preoperative sonography in dermatologic surgery whenever possible as it represents an easy, painless, "in vivo" method, which provides clinicians with significant clinical information that can influence the therapy and improve patient compliance.
