title: Sternoclavicular joint enlargement following block dissection.
abstract: The sternoclavicular joint may become enlarged subsequent to block dissection of the neck. It should be managed conservatively and does not require removal, although both clinical and X-ray appearances may give rise to suspicion of metastasis in the head of the clavicle. A hypothesis of the pathology of this unfamiliar condition is proposed.
