<p>Schwannoma is a slow growing benign peripheral nerve sheath tumor arising from schwann cells. It is also known as neurilemmoma. Although it is common in the head and neck region, it rarely exceeds 10 cm in size. Usually Schwannomas are not larger than 5 to 6 cm in diameter. Large tumors are uncommon and are found in posterior mediastinum or retroperitoneum. We are presenting an unusual giant cell schwannoma over face (cheek) measuring 12×10 cms in size which caused facial deformity to the patient. The tumor was diagnosed on FNAC where cell block was prepared and IHC was done which showed S-100 positivity. This size schwannoma over cheek site has not been reported in the literature as far our knowledge. Therefore this case is unique for its size over face.</p>

“…Schwannoma generally presents as slow growing painless sub-cutaneous or submucosal swelling. Depending on the site of nerve trunk or branch from which it arises, it may be located within the lower part of orbit,[ 7 8 9 ] maxillary sinus[ 3 ] or present as sub-cutaneous mass in infra-orbital region[ 10 11 12 ] [ Table 1 ]. Intraorbital schwannoma generally develop from supraorbital or supratrochlear nerves, and less frequently from infra-orbital nerves.…”

“…[ 8 9 ] Larger lesion involving greater areas of mid-face are treated by extra-oral Weber-Furgusson incision combined with ostectomy[ 13 ] [ Table 1 ]. Although malignant transformation and recurrence of schwannoma is very low, a case of recurrent infra-orbital schwannoma[ 12 ] attributed to incomplete removal of the lesion through a limited skin incision was reported.…”

Extra-cranial schwannomas although common in head and neck region are very rarely seen originating from the infra-orbital nerve. We report a case of schwannoma arising from infra-orbital nerve in a 40-year-old male patient. The case presented as an isolated, asymptomatic, slow growing sub-cutaneous nodular swelling over left side of mid-face. On ultrasonography, a localized lesion within the sub-cutaneous tissue of cheek was observed, without involvement of orbital, maxillary sinus or underlying bone. Aspiration biopsy of the lesion showed spindle shaped cells predominantly arranged in Antoni A pattern around verocay bodies, with less organized Antoni B tissue in few places. Diagnosis of schwannoma, probably arising from terminal branch of infra-orbital nerve was established. The tumor was approached through skin incision. At the time of exploration, the lesion was found to emanate from the nerve trunk of peripheral branch of infra-orbital nerve, which was dissected and preserved. We correlate our experience with previously reported cases of infra-orbital nerve schwannoma.
