Abstract

Schwannomas are benign peripheral nerve neoplasms that arise from Schwann cells. They usually occur in the adult population. The most common site in the head and neck region is the parapharyngeal space. Intrapharyngeal schwannomas are extremely rare, and those that have been reported all occurred in adults. We report what to the best of our knowledge is the first case of an intrapharyngeal schwannoma in a pediatric patient. The patient, a 15-year-old boy, was treated successfully with surgical excision.

Introduction

Schwannomas are benign neurogenic tumors that arise from Schwann cells. They can occur at any age, but their peak incidence is between 20 and 50 years; they are equally distributed between the sexes.1 These neoplasms usually present as a solitary, slowly growing mass.2 Head and neck schwannomas account for 25 to 45% of all cases.3
