A Case of Non-Hodgkin's Lymphoma of the Oral Cavity Presenting as a Buccal Mass

Non-Hodgkin’s lymphoma is a heterogenous group of neoplasm affecting the lymphoid system. About 10% of Non-Hodgkin's lymphoma occur in the extra-nodal region in the head and neck area and more than half of extra-nodal lymphoma in the head and neck area involves the Waldeyer’s ring. Localization in the oral cavity is rare. We experienced one rare case of Non-Hodgkin’s lymphoma in the oral cavity, with trismus and persistent ulcerated swelling in the right-side cheek as the chief complaint.
