Extranodal non-Hodgkin lymphoma of the head and neck presenting as a mandibular swelling: report of two cases.

We report two cases of extranodal extralymphatic non-Hodgkin lymphoma presenting as a mandibular swelling. In one case the masseter muscle was involved, suggestive of a non-epithelial process. In the other case the mandible was involved by a mixed osteolytic bone process. Extranodal non-Hodgkin lymphoma should be considered when dealing with a mass lesion in the masticator space.
