Abstract
PURPOSE: To describe the clinical and histopathological findings in two patients with cystic lesions located in the temporal orbit. METHODS: Case reports. RESULTS: Cystic lesions excised from the temporal orbit of two patients were found to be lined with ciliated pseudostratified epithelium, consistent with a choristoma composed of tissue derived from the respiratory system. A review of the literature suggests that this is an uncommon cause of a cystic orbital mass. CONCLUSIONS: Respiratory choristomatous cysts should be considered in the differential diagnosis of cystic lesions of the temporal orbit.
