What is nail psoriasis?

• A. A condition causing discoloration only
• B. A condition causing pitting, abnormal nail growth, and discoloration
• C. A condition only affecting the nail bed
• D. A mild form of fungus

Answer: (B)

Nail psoriasis is a chronic skin condition that primarily affects the nails and is characterized by several specific symptoms. It can lead to pitting, which are small indentations on the surface of the nail, and may also induce abnormal nail growth patterns, such as thickening or ridges. Additionally, discoloration is a prominent feature, where the nails may appear yellow, brown, or even have a reddish hue due to the underlying inflammation associated with psoriasis.

This combination of pitting, abnormal nail growth, and discoloration collectively indicates nail psoriasis, distinguishing it from other nail conditions which may present with only one or two of these symptoms. Understanding these characteristics helps in diagnosing the condition correctly and providing appropriate treatment.
