Recurrent Infraorbital Rim Osteoma in a Pediatric Patient: A Brief Report.

Orbital osteomas are rare benign tumors, and infraorbital rim involvement is particularly uncommon in pediatric patients. Recurrence after prior excision has been documented only rarely. The authors report a 14-year-old boy with a recurrent osteoma of the left infraorbital rim after previously reported complete excision at an outside institution. On examination, the lesion presented as a firm, painless, well-circumscribed mass without diplopia, proptosis, or visual disturbance. Computed tomography demonstrated a well-defined hyperdense bony lesion arising from the infraorbital rim. Re-excision was performed through a subciliary approach, and histopathologic examination again confirmed compact osteoma. No further recurrence was observed during follow-up. This case demonstrates that infraorbital rim osteomas, which are rare in pediatric patients, may recur even after previously reported complete excision. Careful removal of the lesion together with its periosteal attachment and long-term clinical and radiologic follow-up should be considered in growing patients.
