Patient had diffuse swelling left upper side of the face with periapical radiolucency involving 21, 22, 23 regions and decreased response to electric pulp testing in those teeth. Patient underwent surgical removal of the entire lesion with wide marginal clearance followed by radiation and chemotherapy.
