Abstract

Primary bone lymphoma is a rare entity and it usually occurs in long bones. Primary mandibular involvement is very rare, and it usually shows unspecific features, mimicking odontogenic inflammatory lesions. We present the unusual case of a diffuse large B-cell lymphoma (DLBCL) of the right mandibular body in a 91-year-old woman, who presented with acute pain in the mandibular region initially suspicious for odontogenic abscess. No significant findings were seen on orthopantomography (OPG) and her almost complete edentulism made the diagnosis of abscess unlikely. Computed tomography and magnetic resonance images showed an expansive mass around the right mandibular body with erosion of cortical bone and involving the right mandibular canal and nerve. Final diagnosis of DLBCL was pathologically proven. The presence of odontogenic-like pain in nearly complete edentulism should be suspicious for malignancy, and it needs further diagnostic workup despite the absence of signs on OPG.
