Hutchinson triadA50.5

At the age of 21, Jonathan Hutchinson worked as a medical assistant at St. Bartholomew's Hospital. There he observed 2 children with keratitis and dental abnormalities. The dental changes are known as Hutchinson's teeth or barrel teeth. Hutchinson published his observations in 1858 under the name "chronic interstitial keratitis". In 1861, deafness was also described in this context. Hutchinson summarized keratitis, tooth deformity and deafness as a triad for the diagnosis of congenital syphilis (A53.9).
