[Metastasis of an ameloblastoma to the iliac crest].

A woman aged 31 had an ameloblastoma of the inferior part of the maxilla treated by excision and a bone graft from the iliac crest. Nine years later she presented with a metastasis from the tumour at the donor site. Metastases from an ameloblastoma are rarely encountered. In this case there might have been contamination of the donor site by tumour cells at the time of operation.
