Primary malignant fibrous histiocytoma of the maxilla

Abstract A case of a primary malignant fibrous histiocytoma of the maxilla in a 14-year-old girl is presented. A search of the literature has revealed only one previous case. Primary malignant fibrous histiocytoma is a rare tumour of the jaws which is locally aggressive with little tendency to metastasize, although there have been reports of distant spread. There is no effective treatment but surgery might increase the survival time. The tumour does not respond to radiotherapy or chemotherapy. Recurrence is common, being about 73 per cent. In the present case in spite of early diagnosis and prompt treatment the patient survived for only 10 months.

Benign osteoblastoma of the mandible

Abstract A rare case of benign osteoblastoma involving the mandible is presented. This neoplasm can easily be confused with other bening or malignant lesions of the jaws. The differential diagnosis can be made only by histopathologic examination. The lesion usually does not recur after complete excision.

Burkitt's lymphoma.

The case of a 33-year-old woman with Burkitts lymphoma is presented. This is the third case that has been reported from India. The primary involvement was in the mandible. Endoxan was administered without response. Radiotherapy was resorted to as the second choice of treatment, but metastases developed rapidly in other organs. The patient survived for only 3 months after a diagnostic biopsy.

Adenomatoid odontogenic tumour of the jaws.

Abstract The adenomatoid odontogenic tumour of the jaws is rare. It is important to differentiate it from other odontogenic tumours because of its benign behaviour and this can be reliably done by the histological features.

Ewing's sarcoma of the mandible

Abstract A case of Ewings sarcoma in a young girl with the primary in the mandible is presented. Though trauma has not been established as a definite aetiology, it could have been the initiating factor in this case. The patient was treated by surgical excision followed by radiotherapy. The follow-up is as yet too short to comment upon the postoperative survival.

Melanotic neuroectodermal tumour of the maxilla

Two cases of melanotic neuroectodermal tumour in infancy are reported. The most common site is in the anterior region of the maxilla. Local excision of the tumour is the treatment of choice and in the present cases there has been no recurrence after 12 and 18 months respectively. Histopathological examination is essential and established the diagnosis.
