Orbital respiratory epithelial implantation cyst: A rare case presenting decades after orbital trauma

Abstract

The epithelial implantation cysts are rare complications of orbital trauma or surgery. They arise due to tissue manipulation during surgery secondary to delivery of epithelial cells to deeper areas. We hereby present a case of orbital cyst in an elderly gentleman who became symptomatic with progressive diplopia and proptosis following cranio-orbital trauma. Histopathologic assessment showed a cyst lined by respiratory epithelium. This case also highlights the importance of proper history taking while evaluating orbital cyst for establishing the diagnosis of respiratory epithelial implantation cyst which is a rare entity.
