Use of 22 MHz High-Frequency Ultrasound in the Management of Skin Cancer
Different diagnostic techniques are used to increase sensitivity and specificity of diagnosis with less invasiveness to the patient. One such technique is high-frequency/high-resolution ultrasound (HFUS/HRUS), which provides good discrimination of the different cutaneous layers without secondary effects (Wortsman and Wortsman, J Am Acad Dermatol 62:247–256, 2010). Ultrasound imaging was first proposed as a tool for dermatologist in the late 1970s and first applied to skin cancer diagnosis in the 1980s (Kleinerman et al., J Am Acad Dermatol 67:478–487, 2012; Hoffmann et al., Z Hautkr 64(10):851–852, 1989; Hoffmann et al., Hautarzt 41(6):333–339, 1990). HFUS/HRUS provides specific patterns that can be deduced from images to diagnose certain dermatologic conditions and characterize their behavior (Wortsman and Wortsman, J Am Acad Dermatol 62:247–256, 2010; Desai et al., Dermatol Surg 33:1220–1227, 2007). It is an adjuvant in the diagnosis of skin lesions (Wortsman and Wortsman, J Am Acad Dermatol 62:247–256, 2010), and its use in the study of skin carcinomas is helping dermatologist in therapeutic decision making. This chapter deals on the use of HFUS/HRUS in the management of basal cell carcinomas (BCC).
