Malignant lymphoma (ill defined) .
- Lymphomas are malignant neoplasms of the lymphoid tissue.
- Two major types: Hodgkin’s lymphomas and Non- Hodgkin’s lymphomas.
- Malignant lymphoma manifests as solitary tumor that grows relatively quickly. When the tumor grows, it becomes painful and may cause loosing of the teeth, hypoesthesia of the lower lip or trigeminal neuralgia.
- Radiographically, they appear as ill-defined radiolucencies that may be localized or diffused and sometimes multilocular.
- In Computed Tomography, they are depicted as osteolytic lesions with indistinct borders that may cause destruction of the cortical plates. When they are located in the maxilla they cause destruction of the floor of the nasal cavity and the maxillary sinus.
- Displacement of the adjacent teeth and resorption or thinning of the apices with the characteristic “nail end effect”, are common findings.
