Abstract

INTRODUCTION:

B-cell lymphoblastic lymphoma (B-LBL) rarely occurs in the oral cavity (3.5% of all intra-oral malignant tumors). Few cases of B-LBL mandibular bone involvement have been reported.

OBSERVATION:

We report the case of a 30-year-old female patient presenting with a single swelling of the left mandibular region, having grown for several weeks. Maxillo-facial CT and MRI showed inflammation of soft tissues and muscles without initial signs of osteitis, thus noncontributive to the diagnosis. A biopsy allowed diagnosing an intra-oral bone lymphoblastic lymphoma. The patient was referred to the hematooncology unit for treatment.

DISCUSSION:

Jaw localization of non Hodgkin's lymphoma is rare. Clinical symptomatology and radiological signs are poorly contributive. The diagnosis relies on a histopathological analysis.
