Glenohumeral joint ganglion cyst and other rare cysts of the axilla.

Although ganglion cysts have been reported to arise from almost any joint, those arising from the glenohumeral joint producing an axillary mass are extremely rare. We report what we believe to be the eighth such case and describe its management. The unusual differential diagnosis and aids to diagnosis of axillary cysts are reviewed.

Cost-effectiveness of staging computed tomography of the chest in patients with T2 soft tissue sarcomas.

Background: Published practice guidelines recommend routine chest computed tomography (CT) scanning as part of the staging evaluation for patients with T2 soft tissue sarcomas (STS), although there is no direct evidence to support this practice. The objective of this study was to determine the yield and cost-effectiveness of routine versus selective chest CT scanning for the staging of patients with T2 STS and to identify any subgroups for whom a more selective approach to chest CT scanning could be considered.

Methods: Six hundred consecutive patients with primary, nonthoracic, T2 (> 5 cm) STS underwent both chest X-ray (CXR) and chest CT scanning to evaluate the presence of pulmonary metastatic disease (M1).
