Hutchinson's sign

Hutchinson's sign is a clinical sign which may refer to:

  • A skin lesion on the tip of the nose precedes the development of ophthalmic herpes zoster.[1] This occurs because the nasociliary branch of the trigeminal nerve innervates both the cornea and the tip of the nose. This sign is named after Sir Jonathan Hutchinson.[2]
  • Melanonychia with pigmentation of the proximal nail fold.[3]:671. This is an important sign of subungal melanoma although is not an infallible predictor. Periungual hyperpigmentation occurs in at least one nonmelanoma skin cancer, Bowen's disease of the nail unit. Hyperpigmentation of the nail bed and matrix may reflect through the "transparent" nailfolds simulating Hutchinson's sign.[4]
  • Hutchinson's triad - pattern of presentation of congenital syphilis.
