Congenital syphilis is an infectious disease caused by Treponema pallidum transmitted by infected mother to her baby during pregnancy. Late congenital syphilis is recognised with 2 or more years after birth. One of the main aspects is observed with the triad of Hutchinson, characterised by the presence of interstitial keratitis, eighth nerve deafness and Hutchinson's teeth. This manuscript reports a case of late congenital syphilis presenting with Hutchinson's triad at an age of 7 years. These clinical features are related to syphilis present during pregnancy and at birth, however they commonly become apparent after 5-years of age.
