Fibrous dysplasia of the jaw bone in Jamaica: a review of 15 new cases and 2 cases of recurrence together with a case report - abstract

ABSTRACT

The authors review 15 new cases of fibrous dysplasia of the jaw bone and two cases of recurrence seen in Jamaica between 1980 and 1995, a period of 15 years. Only cases which had histological confirmation to be fibrous dysplasia were included. The clinical behaviour and radiological findings of these cases were studied from the case files, either at the Cornwall Regional Hospital or the Kingston Public Hospital in Jamaica. The present series of 15 new cases of fibrous dysplasia and 2 cases of recurrent fibrous dysplasia of the jaw bone are the first to be documented in Jamaica, accounting for 5.2 percent and 0.68 percent, respectively, of jaw bone tumours in Jamaica. Fibrous dysplasia (excluding recurrent fibrous dysplasia) accounted for 47 percent of all cases of fibro-osseus lesions (WHO classification) seen in Jamaica and recurrent fibrous dysplasia accounted for 6.2 percent of all cases of fibro-osseous lesions seen in Jamaica during this period. One case of fibrous dysplasia presented atypically and is reported in this paper. For the new cases of monostotic fibrous dysplasia, the patients were between the ages of 10 and 47 years, two cases were patients aged 47 years at the time of presentation; this is atypical of what has been previously documented to be the average age at presentation. For these reasons there is need for further study of more new cases in Jamaica. (AU)
