ABSTRACT

Solitary fibrous tumor (SFT) is a rare spindle cell neoplasm that usually develops in the pleura and peritoneum. The head and the neck region is involved in only 6% of the cases. We described a rare case of large SFT originated from the right neck region in a 32-year-old man. Enhanced CT scan revealed two large completely resected masses in the carotid sheath region and the right thyroid gland. Immunohistochemical studies showed positive CD34, CD99, NSE and bcl-2, and negative Desmin, NF, S-100, CD31, F8, CK, MBP, indicating that the tumor was benign. It showed no evidence of recurrence on the patient during 9 years follow-up.
