Abstract:

Objective   To discuss the clinical features， diagnosis， differential diagnosis， treatment principles and prognosis of solitary fibrous tumor(SFT)in the head and the neck． Method   6 cases of head and neck SFT were retrospectively analyzed in clinical features, imaging findings, surgical techniques and postoperative HE staining  immuno-histochemical characteristics of chemistry and prognosis. Results   All were primary healing without significant complications. In a follow-up of 12-28 months, recurrence was not found in 5 patients. 1 patient lost follow-up． Postoperative pathology diagnosis was SFT and of all tumor cells were immunehistochemically positive for CD34 and Vim． Conclusion   SFTs in the head and the neck are rare, and most are clinically benign, occasional with recurrence and metastasis of intermediate tumor. Diagnosis must depends on immune-histochemistry of the whole specimen. Complete radical resection is the first choice of treatment. Long-term close follow-up is mandatory because of aggression in the small number of case.
