This occurred in the right maxillary sinus of a 3-year-old girl. The child came to our clinic with the chief complaint of swelling of the right maxilla. Intraoral examination revealed a swelling of the buccal and palatal gingiva at the right EDC region. Radiographic film showed the abnormal features of diffuse cloudiness of the right maxillary sinus including displacement of a permanent canine tooth bud. The clinical diagnosis was odontogenic tumor. The tumor was resected under general anesthesia.<BR>The histopathological features of the specimens showed malignant lymphoma. We finally diagnosed T-cell acute lymphocytic leukemia with tumor formation. After the operation, antileukemic chemotherapy was undertaken in pediatrics. At follow up, 2 years 7 months postoperatively, she had no sign of recurrence.
