We experienced two cases of giant desmoid tumor around the scapula. Desmoid tumors are also known as aggressive fibromatosis. Resection, however, may be a challenge, because of a high frequency of postoperative recurrence.<BR>Case One: an 18-year-old man was examined for a giant mass on the his left of neck. Physical examination revealed limited shoulder range of motion and muscle weakness in his left arm. Radiographs showed a giant mass stretched from his neck to the ventral scapula. We performed marginal resection of the tumor, but the tumor recurred; therefore, we peformed resection again with radiation therapy.<BR>In case one at present, his shoulder range of motion is still limited, but the tumor has not recurred. Case Two: a 44-year-old woman was examined for a giant mass on her back. Physical examination revealed limited shoulder range of motion and muscle weakness in her right arm. Radiographs showed that the giant mass stretched from her back to the chest wall. We performed marginal resection of the tumor. And in case two at six months after surgery, the tumor had not recurred.<BR>We experienced two cases of giant desmoid tumor around the scapula. At present, there are no recurrences but dysfunction of the shoulder joint and cosmetic problems remained. In order to achieve better functional outcomes,an inter disciplinary approach may be mandatory, especially for large desmoid tumors occurring around the shoulder.
