Solitary fibrous tumor surrounding the carotid sheath

ABSTRACT

Solitary fibrous tumors (SFTs) are rare spindle cell neoplasms that are mostly found arising from the pleura.Although SFTs recently have been reported in other regions, they are rare in the head and neck and have oftenbeen misdiagnosed due to their rarity. SFTs are benign in most cases. Clinically, SFTs usually manifest as wellcircumscribed,slow-growing, smooth and painless masses. Symptoms are often minimal, although they mayinclude sore throat, difficulty in swallowing, change of voice or trismus. CT-Scan and MRI are the most sensitiveimaging procedures used. The treatment of choice is complete surgical excision of the lesion. Because recurrenceshave been noted up to 30 years after surgery, long-term follow up is mandatory. In this article, we present a case ofa Solitary Fibrous Tumor arising in the parapharyngeal space in a 20-year-old man, involving the carotid sheath,treated by surgical excision with no recurrence after 1 year. The clinical presentation, surgical management andpathological findings are described (AU)
