Extranodal diffuse large B cell Non-Hodgkin’s lymphoma of maxilla: An immunohistochemical study based diagnostic approach

Abstract Lymphomas are solid cohesive neoplasm, originating from the cells of immune system, having diverse presentation. NHL is the third most common group of malignant tumors. Incidence of NHL in extra-nodal sites is approximately 20–30%. Diffuse large B cell Non-hodgkin’s lymphoma (DLBCL) is the most common histological variant of lymphoma. This report discusses a case of Non-Hodgkin’s lymphoma in an 80-year male patient with clinical presentation of non-healing painless ulceroproliferative growth, which mimics squamous cell carcinoma.
