Schwannomas, which are benign tumors that arise from Schwann cells in the myelinated nerves, are common soft tissue tumors in the head and neck region. However, the occurrence of schwannomas in the oral cavity is very rare, accounting for only 1% of all schwannomas in the head and neck region. We report a case of a slowly growing schwannoma exceeding 3 cm in size that occurred on the right side of the floor of the mouth in a 21-year-old woman. The patient underwent a magnetic resonance imaging MRI examination and surgical resection. The patient was definitively diagnosed by histopathological examination and immunohistochemical examination.
