title: An unusual swelling in the neck.
abstract: Venous thrombosis is a fundamental pathological entity. Our patient provides an opportunity to consider etiology in terms of Virchow's classic triad. We also draw attention to the effort syndrome, in which recurrent, vigorous exertion of an upper extremity is thought to produce venous thrombosis by virtue of local endothelial trauma.
