Superficial Orbital Rim Osteoma Presented as Palpable Nodules

To report a case of superficial orbital rim osteoma. A 29--year-old woman presented with two small and firm subcutaneous nodule in anterior aspect of the left inferonasal orbital rim. Orbital CT scan showed small well circumscribed exophytic bone density masses on frontal process of maxillary bone. The patient did not undergo surgery at the time of the first referral. After 5 years, she was treated with clinical examination and CT scan according to the growth of the lesion. Complete surgical excision was performed through modified Linch incision. Histopathology evaluation was consistent with ivory type osteoma. Although the orbital rim osteoma often originates from paranasal sinuses and appears as a mass in the orbit with or without superficial components, it may present as subcutaneous nodules on orbital rim.
