In breast cancer, axillary lymph nodes can be classified according to cortical morphologic features. Predominantly hyperechoic nodes (types 1-3) can be considered benign. Generalized cortical lobulation (type 4) is uncommonly a false-negative finding, but metastasis, if present, is invariably detected at sentinel node mapping. The presence of asymmetric focal hypoechoic cortical lobulation (type 5) or a completely hypoechoic node (type 6) should serve as a guideline for universal performance of fine-needle aspiration for preoperative staging of breast cancer. This classification, when verified with larger samples, may serve as a useful clinical guideline if proven with results of in vivo studies.

US-guided percutaneous ablation of small invasive breast carcinomas is feasible and safe.

Bilateral paratracheal and superior mediastinal dissection is an oncologically safe procedure exhibiting minimal morbidity when performed among experienced individuals despite multiple prior surgical procedures or existing vocal cord paralysis.

Bilateral comprehensive level VI/VII dissections are safe and effective for long-term control of recurrent/persistent PTC in the central lymphatic compartment.

The purpose of this report is to describe giant solitary synovial chondromatosis, a previously unrecognized feature of synovial chondromatosis that may histologically and radiographically mimic a malignant neoplasm. Giant solitary synovial chondroma is an intra- and/or extraarticular lesion measuring over 1 cm in size and sometimes as large as 20 cm. The radiographic appearance is that of a large, well-marginated mass either of irregular feathery calcification from coalescence of multiple small synovial chondromas, or a rounded calcified mass from the growth of a single synovial chondroma. Radiographically, giant solitary synovial chondromatosis may appear similar to chondrosarcoma and parosteal osteosarcoma.

Metallic markers were implanted with ultrasonographic guidance in 51 malignant breast tumors in 49 patients to tag the tumor bed in anticipation of complete or almost complete response to preoperative neoadjuvant induction chemotherapy before breast-conservation surgery. The markers were the only remaining evidence of the original tumor site in 47% (23 of 49) of the patients preoperatively. This technique effectively addresses the problem of preoperative localization of the tumor bed in complete or nearly complete response of breast cancer to neoadjuvant chemotherapy.
