Malignant lymphoma (multilocular) .
- Lymphomas are malignant neoplasms of the lymphoid tissue.
- Two major types: Hodgkin’s lymphomas and Non- Hodgkin’s lymphomas.
- Clinically they manifest as solitary tumors that grow 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 can be diffused or localized, 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 occur in the maxilla they usually cause destruction of the floor of the nasal cavity and the maxillary sinus.
- They cause displacement of the adjacent teeth and resorption or thinning of the apices with the characteristic finding of the “nail end effect”.
