Pseudolymphoma is a reactive process involving lymphadenopathy, polyclonal proliferation of B or T-cells, simulating oral lymphoma. With its incidence being very rare, only four cases have been reported in oral cavity with the detailed immunocytochemical examination, which can be due to this entity's unawareness, underdiagnosis or overdiagnosis. It is prerogative to perform immunocytochemical investigations to prevent overdiagnosis as lymphoma, which can be debilitating to the patient. Wherein the treatment of pseudolymphoma initially includes topical or intralesional corticosteroid, antibiotics to surgical and radiotherapy based on its etiology. Herein, we discuss B-cell follicular lymphoid hyperplasia previously diagnosed as small round cell tumor.
