Secondary localized sectoral keratoconjunctival amyloidosis from ocular trauma

To report a case of unilateral localized sectoral conjunctival amyloidosis associated with corneal amyloidosis.

Case report.

A 27-year-old woman with a history of ocular trauma presented with a limbus-based pink-yellow colored superonasal conjunctival lesion with adjacent superonasal sectoral corneal lattice-like changes. The lesion was monitored for 3 years with minimal enlargement, but conjunctival chalasis developed, which was bothersome to the patient. A conjunctival excisional biopsy confirmed the diagnosis of amyloidosis.

To our knowledge, this is the first report of unilateral combined corneal and conjunctival amyloid deposition. Even more unusual was the sectoral distribution of the amyloid. This likely represents a local production and deposition of amyloid.
