Chameleon-like Appearance of Immunotactoid Keratopathy

Abstract

ITK of MGUS can mimic cystinosis, Schnyder corneal dystrophy (CD), pre-Descemet CD, lattice CD, granular CD, arcus lipoides, lecithin-cholesterol acyltransferase deficiency, gelatinous drop-like CD, and Salzmann nodular degeneration. ITK can be the first symptom of MGUS. An annual internal check of MGUS is recommended because of occurrence of a systemic monoclonal gammopathy in 20% of cases.
