Nonendemic Burkitt's lymphoma with jaw involvement: case report.

Toothache of a lower primary molar followed by bilateral swelling of the lower molar regions were the first symptoms of a 6-year-old Finnish male with Burkitt-type malignant lymphoma. Radiographic examination revealed osteolytic changes in the right mandibular and left maxillary quadrant. The cortical bone around the affected teeth was absent and some teeth were grossly displaced. When the therapy was started the teeth returned to their normal positions within a week. Descriptions are given of the jaw lesions, and the clinical, histological, and radiographic diagnosis as well as the clinical course and treatment of the tumor.
