Metastatic ameloblastoma of the skull.
A rare case of a metastatic ameloblastoma of the skull in a 29-year-old woman is reported. An ameloblastoma of the left mandible underwent histological malignant transformation following repeated operations and eventually metastasized to the left temporoparietal region of the skull. The skull tumor showed osteolytic change and marked vascularity in roentgenological examinations. It was removed totally. The histological findings were similar to those of the tumor of the left mandible. The route of the metastasis was considered to be via the left external carotid artery.
