title: Non-Hodgkin's Lymphoma in Buccal Vestibule -Case Report.
abstract: Lymphomas are malignant neoplasms arising from lymphocytes B cell or T cell that affects mainly lymph nodes, spleen and other non hematopoietic tissues. They are classified as Hodgkin's lymphoma (HL) and non-Hodgkin's lymphoma (NHL). Diffuse large B-cell lymphoma (DLBL) is the most common variant of non-Hodgkin's lymphomas and frequently involves extranodal sites. In the oral soft tissues lesions can occur as hard and diffuse tumors involving oral vestibule, gums and posterior region of the hard palate. Most lymphomas, including DLBL arise from B cells are characterized by diffuse population of large cells with cleaved or non cleaved oval nuclei. Both histopathlogical and immunohistochemical (IHC) analysis were strongly advisable for proper management and prognosis. We hereby report a rare case of Diffuse large B-cell variant of non-Hodgkin's lymphoma in a male patient of age 50yrs in left upper buccal vestibule.
