T-cell lymphoma of the oral cavity: case report.

Lymphomas are heterogenous malignancies of the lymphatic system characterized by lymphoid cell proliferation. They can broadly be divided into Hodgkin's lymphoma (HL) and non- Hodgkin's lymphoma (NHL). NHL can originate from B, T, or natural killer (NK) lymphocytes. Extra-nodal 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 an immune-competent patient. The patient was diagnosed to have T-cell NHL on the basis of biopsy and immunohistochemistry, and was referred to oncology department for chemotherapy for definite treatment.
