Composite hemangioendothelioma is a rare vascular tumor. Only 22 cases have been reported previously. We report a case of composite hemangioendothelioma arising in the tongue and review the literature on this lesion. A 38-year-old woman had a mass in the right lateral border of the tongue. It was reddish and approximately 8 mm in diameter. We performed an excisional biopsy. Histological examination revealed a vascular neoplasm composed of a complex admixture of several histological patterns, which were similar to low-grade angiosarcoma, epithelioid hemangioendothelioma, and capillary hemangioma. Tumor cells were exposed at the surgical margins. We diagnosed this lesion to be a composite hemangioendothelioma and re-excised it with a safety margin of 10 mm. There was neither recurrence nor metastasis 36 months after the first excision.
