RESUMO
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)

Malignant neoplasm of the jaws metastatic from primary sit elsewhere in the body do not constitute a numerically large group of lesions. A report of a metastatic neuroblastoma of the adrenal gland to the mandible of a one-year-old infant is described. The tumour was readily diagnosed based on detailed history, clinical examination, roentgenographic features and histologic features. The treatment was that of radiotherapy of the jaw lesion, followed by chemotherapy (AU)

Four cases of fibromatous tumour of the neck occuring in Jamaican children are reported and used to illustrate the concept that although they may create problems of management by local infiltration they are biologically benign. The importance of careful planning of surgery is stressed (AU)

A study of clinical and pathological features in patients presenting with Adamantinoma at the Kingston Public Hospital and the University Hospital of the West Indies from 1958 to 1964 was made. The features found here corresponded with those recorded in the literature and the tumor was found to represent about 42 percent of primary bone tumors in Jamaica (AU)

A case of extensive adamantinoma of the mandible is reported with a review of the literature on the treatment of malignant disease of the mandible. Mandibular resection with immediate autogenous bone graft is recommended as the ideal treatment. The post operative recovery period is short and the cosmetic and functional results are good. The operation is within the scope of the general surgeon. (AU)
