What is a common symptom of nail psoriasis?

• A. Yellowish nails
• B. Clubbing of the nails
• C. Pitting on the surface of the nails
• D. Thickened ridges on the nails

Answer: (C)

Pitting on the surface of the nails is a hallmark symptom of nail psoriasis. This condition is characterized by small dents or depressions that develop on the nail plate, which occur due to the underlying inflammation associated with psoriasis. In nail psoriasis, the rapid turnover of skin cells can disrupt normal nail growth, leading to the formation of these pits. Understanding this symptom is essential for differentiating nail psoriasis from other nail disorders, as pitting is specifically associated with psoriasis and is often one of the first visible signs of the disease.

Other symptoms associated with nail changes, such as yellowish nails, clubbing, or thickened ridges, may occur in different conditions, but they do not specifically indicate nail psoriasis and are thus less significant in identifying this particular disorder.
