However, the intraosseous lipoma is considered a rare bone tumor, that affects the long and flat bones, but it is uncommon in the jaws. Usually, diagnosis based on clinical and radiographic features is insufficient and histopathology analysis is of utmost importance for the final diagnosis.

She had no medical history with medications or genetic diseases. The tooth was extracted with a small soft mass that was subjected to histological analysis and it was found to be an intraosseous lipoma.

The treatment is complete surgical excision.
