The shoulder girdle is a common site for primary and metastatic soft tissue tumor. Clinical presentation could range from asymptomatic, local tenderness to painful limited shoulder range of motion, mimicking impingement syndrome caused by degenerative change of rotator cuff tendinopathy and subacromial enthesophyte, especially when the tumor mass is large enough and within the subacromial space. Generally, open surgery for complete marginal excision is considered to be the standard management for these conditions. We report a case of a 47-year-old female with chronic shoulder pain caused by a benign fibrotic nodule measuring up to 5cm located withing the rotator cuff muscles mimicking impingement syndrome. Arthroscopic excision was performed via standard posterolateral and slightly enlarged lateral portals, with complete symptom resolution and no recurrence at six months. This highlight utility of arthroscopy for managing medium to large size, benign subacromial lesions.
