Introduction: Osteoid osteoma (OO) is a benign osteoblastic tumor which constitutes about 3% of all the primary bone tumors, about 10% of all the osseous benign tumors. Only 1% of the cases occur in the jaws. The present case reports a painless osteoid osteoma, which is a rarity. Case presentation: A 35 year old male patient reported with a bony hard swelling on anterior part of hard palate. Radiograph showed a small radiopacity along the root of maxillary right central incisor. A provisional diagnosis of peripheral ossifying fibroma was made. An excisional biopsy under local anesthesia was performed. Platelet rich fibrin obtained from patient’s blood was used as a surgical dressing. Healing was uneventful at the biopsy site. Histopathological investigation revealed it to be a benign bone forming tumor- a rare variant of osteoid osteoma with the absence of characteristic pain. Conclusion: Osteoid osteoma is a benign tumor that occurs rarely in jaw bones. The present case reports a painless variant of osteoid osteoma of anterior part of hard palate in a young adult. This will add a rare variant of an otherwise rare lesion to the present sparse literature of osteoid osteoma.
