Sternoclavicular joint enlargement following block dissection.
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.
