Hybrid Neurofibroma-Schwannoma of the Orbit

Abstract

Purpose: To report a case of an unusual orbital tumor with histologic features of both neurofibroma and schwannoma. Methods: Clinical and pathological findings are presented in a patient with an orbital tumor. Results: Orbital magnetic resonance imaging in a 51-year-old female revealed a heterogeneously enhancing right orbital mass. An anterior orbitotomy was performed, and pathological evaluation revealed a tumor with discrete areas of both neurofibroma and schwannoma. Conclusions: Hybrid neurofibroma-schwannomas may arise within the orbit.
