NON HODGKINS LYMPHOMA OF ORAL CAVITY

Lymphoma is a malignant disease with two forms: Hodgkin's lymphoma (HL) and non-Hodgkin's lymphoma (NHL). Non-Hodgkin's lymphoma is diagnosed in extranodal sites in 40% of cases, and the head and neck region is the second most affected, with an incidence of 11–33%, while HL has a very low incidence in extranodal sites (1–4%). Among the intraoral findings, the most frequent are ulcerations, pain, swelling, and tooth mobility, while the extraoral findings included facial asymmetry and cervical, submandibular, and submental lymphadenopathy. The few studies reporting imaging findings, the lesions include hypodense lesions with diffuse boundaries, bone resorptions, and tooth displacements.
