Examination by ultrasonography (US) is a rapid, sensitive, cost-effective, and even portable technique for confirming the presence of tumors. However, US is not routinely used worldwide for the diagnostic work-up of cutaneous malignant melanoma. High-resolution US using a 6-14 MHz or 5-13 MHz linear transducer enables the preoperative assessment of tumor size and thickness. Compared with physic...
