A rare case of benign isolated schwannoma in the inferior orbit

Abstract

A rare case of unilateral orbital schwannoma arising from the infraorbital nerve is presented. An excision biopsy with complete removal of the mass in the inferior orbit was performed. A definitive diagnosis was made on histopathological examination. The clinical and histological features of schwannoma are discussed. A need for early removal of such tumors is recommended to prevent complications.

Orbital intraconal abducens nerve schwannoma: A case report and review of the literature

“…Intraorbital schwannomas may arise from different nerves; sometimes, it may be difficult to identify their true origin. [ 2 ] Those arising from the sensory branches of trigeminal nerve are located in superior and medial quadrants of orbit,[ 3 ] those arising from infraorbital nerve are in inferior quadrants[ 4 ] and schwannomas arising from the motor nerves usually arise at their respective myoneural junction. The literature search has identified only three other abducens nerve schwannomas of the orbit.…”

Orbital Schwannoma: Case Report and Review

“…Orbital schwannomas are rare, presenting frequency between 1 and 5% of all orbit neoplasms, with age variation from 20 to 70 years old and without gender prevalence. [1][2][3]6 In general, schwannomas originate from sensory nerves. In the case of orbital schwannomas, it is not different, with the supratrochlear and supraorbital nerves being the ones most frequently affected.…”
