RESUMEN
Amyloidosis is a disorder of protein metabolism in which amyloid can be accumulated in various tissues of the body. Primary localized amyloidosis can affect the bulbar or palpebral conjuctiva, Tenon`s capsule, tarsus, limbus, lacrimal gland, or orbit. Especially secondary localized amyloidosis of the cornea can occur after trauma. scar, and corneal opacity or can be associated with a chronic ocular inflammatory disorder. The authors diagnosed the secondary localized amyloidosis that developed in a 53-years-old female patient who had undergone penetrating keratoplasty. The diagnosis was confirmed by hematoxylin-eosin and Congo red staining, and transmission electron microscopic examination.

Amyloidosis may be defined as a group of disorders of extracellular deposition of the fibrous protein amyloid in one or more sites of body with variable causes and pathogenesis which have in common characteristic histopathologic features. Primary localized corneal amyloidosis is confined in the cornea and has not the evidence of apparent preexisting disorder or systemic involvement. The incidence has been reported rare. We have experienced one case of corneal amyloidosis which is confirmed by the histopathologic evaluation. We report this rare case with literatures reviews.
