Wide Resection Preserving Conjoined Tendons of the Rotator Cuff Muscles for Undifferentiated Pleomorphic Sarcoma at...

Surgical principles in sarcoma are a wide resection, including surrounding tissues and maximisation of the function of the affected limb. Rotator cuff muscles are biomechanically important structures acting as a force couple in movement of the shoulder joint. Thus, conjoined tendons are essential for motion capability in absence of the supraspinatus muscle. This article reports a case of a large undifferentiated pleomorphic sarcoma (UPS) at the suprascapular fossa in a 78-year-old man. After diagnosis of sarcoma, he underwent wide, en-bloc excision preserving conjoined tendons of rotator cuff muscles and low-dose radiation therapy for surveillance of local recurrence. All dissection was performed to avoid contaminating the tumour and involved the whole supraspinatus except the conjoined tendons. We report a case of UPS at the suprascapular fossa, which showed a good result after a wide resection preserving conjoined tendons of rotator cuff muscles. Level of Evidence: Level V (Therapeutic).
