title: Diffuse large B-cell lymphoma (extranodal) of maxillary buccal vestibule.
abstract: Lymphomas are the group of neoplasms originating from lymphoreticular system mainly from lymph nodes, among them up to 40% of non-Hodgkin's lymphomas present extra nodally. In oral cavity, lymphomas are least common and account for 3-5% of all malignancies, presenting mainly in older age groups with male predominance. According to Revised European-American Lymphoma classification, among B-cell and T-cell subtypes of non-Hodgkin's lymphomas, diffuse large B-cell lymphoma (DLBCL) is the most common, characterized by diffuse proliferation of large neoplastic B lymphoid cells. Here we present a case report of DLBCL affecting oral cavity involving left buccal vestibule and extending onto the palate, along with its clinical, histopathologic and immunohistochemical features.
