Glomangiomatosis: a case report.

Glomangiomatosis is a benign vascular variant of a glomus tumor. The lesion represents only 5% of glomus tumors with unusual or atypical features and even fewer glomus tumors with typical features. The lesions are most commonly located in the distal extremities and are multiple, deep, extensive, and often pain producing.

Displaceability of SLAP lesion on shoulder MR arthrography with external rotation position.

Objective: To investigate the usefulness of the external rotation (ER) position on magnetic resonance (MR) arthrography for the diagnosis of superior labral anterior to posterior (SLAP) lesion.

Materials And Methods: Approval of institutional review board was obtained, and informed consent was waived. The MR arthrograms of 210 shoulders that were arthroscopically confirmed as SLAP lesion in 163 shoulders and intact superior labrum in 47 shoulders were retrospectively reviewed in each neutral and ER position for the diagnosis of SLAP lesion, the extent of distraction of the torn labrum, and the external rotation angle.

Primary alveolar soft part sarcoma of fibula demonstrating ASPL-TFE3 fusion: a case report and review of the literature.

Alveolar soft part sarcoma is a rare soft tissue tumor typically affecting young adults. These tumors are most often seen in the deep soft tissues of the extremities and patients generally present with advanced disease. Primary bone involvement is extremely rare and has only been reported in seven cases.

The accuracy of subacromial corticosteroid injections: a comparison of multiple methods.

Corticosteroids are commonly used in the treatment of the impingement syndrome. Efficacy, as well as accurate placement, have been questioned. The purpose of this prospective, randomized study is to assess the accuracy of subacromial injections and to correlate accuracy with short term clinical outcome at 3 months.
