Solitary fibrous tumor (SFT) is a relatively rare myofibroblastic tumor involving the pleura and peritoneum in most cases. Recently, SFTs arising various sites of the body have been described. The 2013 WHO classification of tumors of soft tissue and bone defines SFT an intermediate-grade tumor that is benign. However, distant metastases have been reported in about 10% of cases.
We report a rare case of SFT of the neck. The patient was a 75-year-old female who presented with the complaint of swelling of the right neck. Her previous doctor suspected schwannoma and referred her to our center for operation. However, the findings of fine-needle aspiration biopsy, computed tomography and magnetic resonance imaging were atypical. Therefore, we performed resection of the tumor to obtain a final diagnosis. Histopathology of the resected tumor revealed the diagnosis of SFT. This case serves to emphasize that in the differential diagnosis of tumors of the neck, it is important to bear in mind the possibility of SFT.
