title: Metastasis of greater wing of sphenoid bone in bronchogenic carcinoma: a unusual case report.
abstract: Orbital metastasis in systemic cancer is known to occur and occurs in up to 7% of all systemic cancers. Orbital features typically present after the diagnosis of the primary tumor. In about 20% of cases, there is no known primary cancer at the time of presentation with orbital metastatic disease. Here we report a case of a 60-year-old male smoker, in whom proptosis, due to metastasis in greater wing of left sphenoid bone secondary to bronchogenic carcinoma, was the initial symptom. We could not find in literature metastasis to greater wing of sphenoid bone due to small cell carcinoma of lung.
