Dermatology · STI: congenital syphilis

Sample item

Which triad is characteristic of late congenital syphilis?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Hutchinson teeth, interstitial keratitis and eighth nerve deafness

Hutchinson triad consists of notched peg-shaped upper incisors, interstitial keratitis and sensorineural deafness. It is a late manifestation appearing after 2 years of age.

Option by option

  • A. Patent ductus arteriosus, cataract and deafness

    This combination describes congenital rubella syndrome.

  • B. Mulberry molars, hepatosplenomegaly and jaundice

    Mulberry molars are late features but hepatosplenomegaly is early, so this is not the triad.

  • C. Saddle nose, snuffles and pemphigus

    Snuffles and pemphigus belong to early congenital syphilis.

  • D. Hutchinson teeth, interstitial keratitis and eighth nerve deafness (correct)

    Correct. This is the Hutchinson triad.
