A rare teratologic disease caused by vertical transmission of the spirochete <i>Treponema pallidum</i> from an infected mother to the fetus, characterized by early congenital syphilis during the first two years of life (maculopapular rash progressing to desquamation, hepatosplenomegaly, osteochondritis, snuffles, and iritis), followed by late congenital syphilis with the classic Hutchinson's triad of Hutchinson's teeth, interstitial keratitis, and eighth nerve deafness. Additional signs may include saddle nose, saber shins, seizures, and mental retardation. Congenital syphilis can also result in stillbirth, neonatal death, and nonimmune hydrops. [from ORDO]

A contagious bacterial infection caused by the spirochete Treponema pallidum. It is a sexually transmitted disorder, although it can also be transmitted from the mother to the fetus in utero. Typically, it is initially manifested with a single sore which heals without treatment. If the infection is left untreated, the initial stage is followed by skin rash and mucous membrane lesions. A late stage follows, which is characterized by damage of the internal organs, including the nervous system. [from NCI]
