Lymphomas are heterogeneous malignancies of the lymphatic system characterized by lymphoid cell proliferation. They can broadly be divided into Hodgkin's lymphoma (HL) and non-HL (NHL). NHL can originate from B, T or natural killer lymphocytes. Extranodal presentation of T-cell NHL is extremely rare and is often seen in immunocompromised individuals. Here, we report a rare case of T-cell lymphoma of the oral cavity in a 13-year-old patient. The patient was diagnosed to have T-cell lymphoma on the basis of biopsy and immunohistochemistry and was referred to the oral surgery department for definite treatment.
