Occurrence of pathological conditions of the jaw bone in Jamaica

Objectives: Histopathologically confirmed jaw bone tumours in Jamaica were studied retrospectively in order to enable comparison with what has been previously documented by other authors throughout the world. No such study has been previously carried out in the English-speaking Caribbean. Materials and Methods: The dockets (case files) of patients who had tumours and pathological conditions affecting the jaw bone in Jamaica between 1980 and April 1995 were retrieved from the record department of both the Kingston Public and Cornwall Regional Hospitals in Jamaica. Only cases with histopathological confirmation were studied except for oral tori. A total of 229 jaw bone tumours were recorded and information such as age, sex, site of lesion, clinical behaviour and radiographic appearance was documented. Our results were compared with the findings of other authors. Results: A total of 229 jaw bone tumours were analysed with special emphasis on radiology. Jaw bone tumours of odontogenic origin accounted for 53.3 percent of all jaw bone tumours in Jamaica. Of these 70 (57 percent) were odontogenic tumours and 42 (34 percent) were odontogenic cyst. Of the 32 cases of fibro-osseous lesions, 15 (47 percent) were fibrous dysplasia and surprisingly three cases (9.4 percent) were gigantiform cementoma. No case of cementifying fibroma was recorded. Conclusions: Some aspects of the pathological conditions of the Jaw bone differs from what has been previously documented by other authors from other parts of the world.(AU)

Benign fibro-osseous lesions of the jaw bones in Jamaica: analysis of 32 cases and report of a case

All the cases of benign fibro-osseous lesions seen at the two major public hospitals in Jamaica over a 15 year period were analysed and the results compared with what has been previously documented by the authors. No such analysis has been carried out in Jamaica or elsewhere in English speaking Caribbean. The case files of patients histologically diagnosed as having fibro-osseous lesions at both the Kingston Public Hospital and the Cornwall Regional Hospital in Jamaica from 1980 to 1995 (a period of 15 years) were retrieved and information about the lesions was documented. The WHO classification for benign fibro-osseous lesions was used. 32 cases of benign fibro-osseous lesions were recorded over the 15 year period. Of these, 15 were histologically reported as fibrous dysplasia, 10 as ossifying fibroma, 3 as gigantiform cementoma, 1 each as peripheral cemental dysplasia and cementoblastoma, and two cases of recurrent fibrous dysplasia.(AU)

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

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)

Radiology of ameloblastoma in Jamaica

AIMS: The radiographic characteristics of ameloblastoma are presented for 47 primary and 12 recurrent lesions found in Jamaica. While ameloblastoma is well-documented elsewhere in the world, this is not the case for Jamaica. MATERIAL AND METHODS: All cases of histologically confirmed ameloblastoma seen in Jamaica between 1980 and 1995 were reviewed with special attention being paid to the radiologic appearance. RESULTS: Twenty-seven (57 percent) of the primary cases were multilocular radiolucencies while 43 percent were unilocular and radiologically well defined. Root resorption was found in most instances irrespective of the presence of internal septae. Forty-four cases (94 percent) involved the mandible, with one presenting bilaterally and almost symmetrically in the posterior mandible. Three cases involved the maxilla of which one also involved the mandible on the same side, a case of unilateral involvement of both mandible and maxilla in the same patient. Recurrent ameloblastoma presented as cystic unilocular or multilocular radiolucencies of the mandible in the are mesial or distal to the operation site, and extension within the bone graft was also found. CONCLUSIONS: The appearance of ameloblastoma in Jamaica, with few exceptions, is similar to that described elsewhere.(AU)

A 15-year study of jaw bone tumours in Jamaica (1980-1995) with specific emphasis on radiology

Jaw-bone tumours were studied retrospectively from data obtained from the Department of Oral and Maxillofacial Surgery at both the Kingston Public Hospital and the Cornwall Regional Hospital in Jamaica . In this study special emphasis was placed on the radiological aspect of jaw-bone tumours. As far as we are aware, no such study has been previously carried out in the English speaking Caribbean. This study is of great interest because it utilizes previously unreported clinical materials to document aspects of jaw-bone tumours in Jamaica which will allow for a comparison with what has previously been documented by other authors throughout the world. A computer programme called "Tumour Power House" was developed to be used on an IBM or Macintosh computer, for use on a continuous basis for tumour registering. A total of 293 jaw-bone tumours has currently been analysed with special emphasis on radiology. Jaw-bone tumours of odontogenic origin accounted for 42 percent of all jaw-bone tumours in Jamaica. Of these, 70 (57 percent) were odontogenic tumours and 42 (34 percent) were odontogenic cysts. The 32 cases of fibro-osseous lesions during this period represents approximately 11 percent of the total number of jaw-bone tumours in Jamaica. Of the 32 cases of fibro-osseous lesions 15 (47 percent), were fibrous dysplasia and surprisingly, three cases (9.4 percent) were gigantiform cementoma, thus adding to the few numbers in the literature. No case of cementifying fibroma was recorded (AU)

Burkitt's lymphoma in Jamaica: report of the first case with cytological, histochemical and electron microscopic studies

A case is reported of a 9-year-old Jamaican negro boy with Burkitt's lymphoma who presented with advanced disease (Stage IV). He died within 4 months of the onset of his illness. The patient had the classical clinical and pathological features as seen in Africa and the latter was confirmed by detailed histological, cytological, histochemical and ultrastructural studies. This is the first report of an authentic human case of Burkitt's lymphoma in Jamaica (AU)

Total resection of the upper jaw

A case is presented for the operation of total resection of the maxilla in the treatment of neoplasms of the upper jaw. The satisfactory results obtained with a technique involving the use of epithelial inlay and maxillo-facial prosthesis, are described. Modification of the recognised operative procedures are indicated. (AU)
