Mandibular soft tissue mass as the initial presentation of Burkitt's lymphoma.

A six-year-old girl was evaluated for an intraoral mass of 5 months duration, which had been treated with antibiotics in a district hospital. Extraoral examination showed a firm, non-tender swelling at the angular region of the left mandible with regional lymphadenopathy. Intraoral examination revealed a mass extending from the left mandibular primary first molar to the retromolar region, interfering normal occlusion.
