A 3 years old girl presented to our ENT Department with  two months history of  progressively enlarging swelling over the chin. It extended intra-orally and involved the floor of the mouth. There were no clinically palpable neck nodes. Radiologically, osteolysis of the mandible was noted. Histopathology of the initial incisional biopsy revealed numerous multinucleate giant cells scattered in a fibrovascular stroma. The child underwent surgical resection with titanium plate reconstruction of the defect and had uneventful postoperative course.
KEY WORDS: Osteoclastoma. Giant cell tumour.  Symphysis menti tumours.
