Extranodal large B cell lymphoma of the anterior maxilla. Case report and review of literature.

In the oral cavity, lymphoproliferative disorders can manifest in various ways, often as an extranodal externalization. In the case presented here, it was a B cell lymphoma originating in the periapical bone of the anterior maxilla. X-ray revealed a periapical radiolucency associated with an intact tooth with no decay, fillings or history of trauma. The tooth tested non-vital. After root canal treatment, an apicoectomy was performed with a biopsy. The most common diagnosis would be of dental etiology. The pathology report revealed a non-Hodgkin's B cell lymphoma. Most often, this disease appears as localized dental or oral pathology. Non-specific signs and symptoms present in association with lymphoproliferative disorders include lymphadenopathy, trismus, pain, swelling, sinusitis, fever, sepsis, prosthetic instability and paresthesia. Early detection results in decreased morbidity and a better prognosis for the patient.
