Glomus tumor of the scapular neck with axillary nerve compression at the shoulder. A case report.

Background: Glomus tumors, also known as benign acral tumors are extremely rare. Previous glomus tumors from other regions of the body have been linked to neurological compression symptoms, however axillary compression at the scapular neck has never been described. Case presentation: Here, we report a case of axillary nerve compression in a 47-year-old man, secondary to a glomus tumor of the neck of the right scapula, initially misdiagnosed with biceps tenodesis performed and no pain improvement. The magnetic resonance imaging demonstrated a well-contoured, 12 mm tumefaction at the inferior pole of the scapular neck T2-hyperintense and T1-isointense and interpreted as a neuroma. An axillary approach allowed the dissection of the axillary nerve, and the tumor was completely removed. The pathological anatomical analysis resulted in a nodular red lesion measuring 14 × 10 mm, delimited and encapsulated with a definitive diagnostic of glomus tumor. The neurologic symptoms and pain disappeared 3 weeks after surgery and the patient reported satisfaction with the surgical procedure. After 3 months, the results remain stable with a complete resolution of the symptoms. Conclusions: In cases of unexplained and atypical pain in the axillary area, and to avoid potential misdiagnoses and inappropriate treatments, an in-depth exploration for a compressive tumor should be performed as a differential diagnosis.

Arthroscopic Management of Glenohumeral Arthritis.

Glenohumeral arthritis in the young adult is a particularly challenging condition for which optimal treatment algorithms have yet to be established. Arthroscopic joint-preserving treatments have the advantage of delaying arthroplasty in this younger population while maintaining the patient's natural anatomy and do not appear to compromise later arthroplasty. Various surgical techniques are available such that the overall procedure is tailored to the patient's individual pathology. Most short- and mid-term studies show good outcomes with low conversion to total shoulder arthroplasty and sustained improvements in functional outcome scores.
