Diffuse Large B Cell Lymphomas (DLBCL) encompasses a heterogeneous group of tumors that together constitute the commonest of all Non Hodgkin Lymphoma (NHL) and the proclivity of DLBCL to oral cavity is unknown. They mostly arise from soft tissues as asymptomatic lesions, mostly without ‘B’ symptoms and involvement of jaw bones is uncommon. Most studies and case reports of oral DLBCL’s are based on, manifestation of primary extra-nodal disease or a component of a disseminated disease process involving regional lymph nodes. Many investigators have proposed that patients with this cell type who maintain a complete response for 24 consecutive months are cured because late relapses seldom occur. With advances in treatment modalities, many patients with NHL become long-term survivors and the risk of relapses or second tumors are of growing concern. We present a case of DLBCL which relapsed after five years of initial lesion in a 41 year old female patient and presented as a nonspecific bilateral anterior maxillary radiolucency. DLBCL usually express pan-B markers with small percentage expressing T-cell markers. Few rare cases of DLBCL have shown CD3 expression, which is a most sensitive T-cell marker which was focally expressed in the present case.
