Abstract

We report the rare case of a central giant cell granuloma of the hard palate. A 30-year-old Japanese woman consulted our clinic because of a swelling of the hard palate. MRI examination showed a well-demarcated homogenous lesion of the hard palate with low signal intensity on T1-weighted images and high signal intensity on STIR. CT revealed a deep crater-like bone defect adjacent to the incisive foramen. Surgical excision was performed with the patient under general anesthesia. Histopathological examination revealed dense proliferation of spindle-shaped cells accompanied by blood capillaries ans multinucleated giant cells. The lesion was diagnosed to be a central giant cell granuloma. There has been no evidence of recurrence as of 17 months after the operation.
