Case Report (n=1)
Wide local excision of an exophytic pedunculated undifferentiated pleomorphic sarcoma on the scapula resulted in no recurrence or metastases at two years.
Single case of pedunculated scapular undifferentiated pleomorphic sarcoma does not alter practice; leaves open refined diagnostic criteria for atypical sites.
Undifferentiated pleomorphic sarcoma is a common soft tissue sarcoma. Unfortunately, any attempt to describe the line of differentiation fails. It represents a final common pathway in tumors that undergoes progression towards dedifferentiation. We report a man with an undifferentiated pleomorphic sarcoma presenting as an exophytic pedunculated tumor of the left scapula. Histopathology analysis revealed spindle-shaped cells with great pleomorphism and numerous mitoses. Immunohistochemistry showed diffuse expression of vimentin. Wide local excision was performed after an oncology consultation. After two-years of follow-up, the patient has shown no evidence of recurrence or metastases.
