Background: Peripheral T-Cell Lymphoma Not Otherwise Specified (PTCL-NOS) is a rare type of non-Hodgkin T-cell lymphoma which frequently seen in immunocompromised individuals. It is estimated that only 2% of lymphomas are located on the buccal mucosa. In this case report, we present a 34-year-old male with a PTCL diagnosis.

Case: A 34-year-old immune-competent male presented with a buccal progressive ulcerated lesion. Histopathologic and immunohistochemical findings were compatible with PTCL-NOS and classified as stage IIEA according to the Ann Arbor staging. The patient underwent chemotherapy followed by radiotherapy. He remained disease-free after 12 months of follow-up.

Conclusion: Although lymphoma is uncommon in the oral cavity, physicians especially dentists in ordinary dental checkups should consider persistent progressive lesions as an important differential diagnosis of lymphoma.
