Tongue base lesions have a diverse and extensive etiology. One of the benign tongue base lesions is schwannoma. Schwannoma and neurofibroma are two tumors of the peripheral nerves originating in the nerve sheaths. Schwannoma account for just over 1% of benign tumors which have been reported in the oral cavity and base of the tongue and with regard to its involved area in the oral cavity is very rare. Here, we report a case of a 13-years-old girl with a schwannoma in the base of tongue, without any symptoms or signs that explored accidentally.
