This paper describes a case of Burkitt lymphoma involving the right side of the maxillary gingiva that was accompanied by bone marrow metastasis in a 2-year-7-month-old boy. Epstein-Barr virus (EBV) infection was suggested to be involved.
On July 23, 1996, an exploratory excision was performed. A histopathologic diagnosis of malignant lymphoma was made. A computed tomographic scan revealed an extended tumor in the right maxillary deciduous molar region. A high signal field was noted bilaterally in the paranasal sinus on T 2-emphasized magnetic resonance images of the primary site. Ga and Tc scintillation scanning showed marked accumulation in the right temporal and left parietal regions, while systemic imaging showed abnormal accumulation in the right cranial, left parietal, and right iliac regions.
The histopathologic diagnosis was malignant lymphoma, diffuse small non-cleaved (Burkitt), Stage IV.
Chemotherapy was initiated on July 30. About 1 year after the initiation of therapy, not only the primary site but also the metastatic foci in the bone and bone marrow have disappeared.
