Osteoma is a benign, slow growing, rare osteogenic tumor arising from the proliferation of cancellous or compact bone. They are rarely seen in either of the jaw but commonly seen in other long bones of the body. They are of three types- central, peripheral, and extra skeletal. The peripheral type is the most rarely occurring osteoma in jaw. Osteomas are usually asymptomatic and are observed on routine clinical and radiographic examination. This article presents two rare cases of large solitary peripheral osteoma, located at the inferior border of mandible and posterior palatal bone; with an emphasis on reviewing the published literature, differential diagnosis along with use of various diagnostic imaging resources for this bone defect.
