An unusual presentation of a swollen arm: a case report.
BACKGROUND
Subclavian vein thrombosis is a rare but potentially fatal condition that most often occurs iatrogenically or in the context of malignancy. Here we report the case of an active, healthy 32-year-old woman who presented with subtle findings of arm pain, paresthesias and skin changes of acute onset and was subsequently diagnosed with upper extremity deep vein thrombosis and subclavian stenosis, and was started on a course of oral antithrombotics.


METHODS
A 32-year-old right-handed Caucasian woman presented to her family medicine clinic with left shoulder pain and numbness along her ipsilateral forearm and hand, as well as subtle swelling of the affected limb. Initially diagnosed with medial epicondylitis, she was later diagnosed with subclavian thrombosis caused by Paget-Schröetter syndrome.


CONCLUSIONS
Presentations such as these are often attributable to soft-tissue injuries that resolve with rest and sometimes physiotherapy. Subclavian thrombosis was a highly unexpected diagnosis in this case; however, family physicians must remain vigilant in considering rare causes of common clinical presentations which could cause patients significant morbidity if left undiagnosed.
