Meningioma is a brain tumor arising from the meninges, which is extremely rare extracranial. We report an ectopic meningioma of the tongue. A 39-year-old man was referred to our hospital with the chief complaint of a tongue mass. Biopsy revealed a benign tumor, which was surgically removed from the tongue under general anesthesia. Pathological findings showed characteristic spiral growth of tumor cells, and immunostaining was epithelial membrane antigen positive. The pathological diagnosis was a meningioma. After surgery, the whole body was examined and no similar lesion was found. There has been no sign of recurrence as of 2 years after the operation.
