Oral and maxillofacial tumours in Northern Nigeria: an analysis over five years.

A clinical and histopathological review of 200 oral and maxillofacial tumours seen at the Maxillofacial Unit at Kaduna, Nigeria during a five-year period is presented. A large number of these were odontogenic tumours, bone tumours and tumours of the maxillary antrum. Some of the unusual histological features seen are discussed. One feature of particular interest was the large number of osteosarcomas, chondrosarcomas, fibrous dysplasias and ossifying fibromas of the jaw bones, as opposed to the long bones.
