Intraoral Schwannoma - Diagnosed by Fine Needle Aspiration Cytology: Report of Two Cases

Abstract

Schwannomas are benign nerve sheath derived tumours and frequently involve the head and neck region. Intraoral involvement is rare and is seen in 1% of cases. Predilection of the lesion intraorally seen more in tongue followed by palate, floor of mouth, buccal mucosa, least in lips and jaws. Fine Needle Aspiration Cytology (FNAC) plays an important role for the preoperative diagnosis and to preserve the nerve function during surgery. We present two cases of intraoral schwannomas diagnosed by FNAC and in one case immunocytochemistry with S-100 was also done to aid to the diagnosis.
