Gastrointestinal Tumor Research and Treatment

Schwannoma (neurilemmoma) is a slow-growing benign tumor of the nerve sheath derived from Schwann cells. Approximately 25% to 48% of all schwannomas are seen in the head and neck region. In rare cases, these lesions may affect the oral cavity. They are usually asymptomatic, do not recur, and rarely undergo malignant transformation. Intraorally, the tongue is the most common site, followed by the palate and floor of the mouth. Man, 66, had an asymptomatic nodular lesion on the tip of tongue for about 4 years. The main clinical proposed diagnoses were benign mesenchymal tumors and salivary gland tumors. An excisional biopsy was performed and the histopathological analysis led to a diagnosis of schwannoma. The patient recovered well and is in follow-up with no abnormalities.
