Schwannomas are infrequent tumours of oral cavity that are not routinely included in the differential diagnosis of oropharyngeal masses. The tumour presents with non-specific clinical symptoms and is clinically indistinguishable from varied soft tissue neoplasms of the oral cavity. Of the 84 cases of lingual schwannoma reported in English literature in the past 61 years, only 18 cases have been reported in paediatric age group ranging from 1 to 15 years. We, herein, report a rare case of schwannoma of the tongue in a 14-year-old boy, presented as a painless swelling with characteristic Antoni A and Antoni B pattern with Verocay bodies on histopathology. Strongly positive immunohistochemical staining with S 100 protein confirmed the Schwann cell origin.
