We evaluated the value of ultrasound-guided needle biopsy in 20 soft tissues masses about superficial bone lesions in 20 oncology patients. Sonographically guided needle biopsies were performed without an on-site pathologist. A diagnostic sensitivity of 95% and specificity of 100% in separating a benign or a malignant lesion was obtained. Fine needle aspiration cytology allowed the specific cell type of malignancy to be diagnosed in 80% of cases, while core needle biopsy allowed it in 91%. Real-time ultrasonographic guidance permits precise needle placement into the targets, avoidance of hypervascular areas, and flexibility of patient positioning so that needle biopsy can be performed quickly and safely on soft tissue masses about superficial bone lesions.
