Hybrid Neurofibroma/Schwannoma of the Orbit.

A 68-year-old female presented for assessment of a space occupying lesion of her right orbit, demonstrated on MRI. An upper lid crease anterior orbitotomy was performed and the lesion excised completely. Postoperatively, she had reduced sensation in the distribution of the supraorbital nerve. Histopathologic examination of the excised lesion revealed a hybrid neurofibroma/schwannoma. This represents the fourth reported case of such a lesion arising within the orbit.
