Which nail condition could signify an underlying illness or injury?

  1. Onychomycosis Unguium

  2. Hang Nails

  3. Corrugations

  4. Verruca

The correct answer is: Corrugations

Corrugations, or vertical ridges or grooves on the nail, can be a sign of an underlying issue such as nutritional deficiencies, psoriasis, or arthritis. Onychomycosis Unguium, also known as toenail fungus, is typically a localized infection and does not necessarily indicate an underlying illness. Hang nails and verruca (warts) are common nail issues that can occur but are not typically linked to larger health concerns.
