The body regions covered in this clinical scenario include the neck, chest, abdomen, pelvis, humerus/upper arm, shoulder, elbow, forearm, wrist, hand, hip, femur/thigh, knee, tibia/lower leg, ankle, and foot. US Area of Interest Ultrasound (US) has become increasingly recognized as an excellent triage tool for evaluation of superficial soft tissue masses [12-15]. This recognition has been further supported by a recent prospective study of 219 histologically proven masses that showed US had a sensitivity, specificity, positive predictive value, and negative predictive value of 93.3%, 97.9%, 45.2%, and 99.9%, respectively, for discriminating benign from malignant tumors in the superficial soft tissues [16].
