What are common symptoms of nail psoriasis?

• A. Pitting, ridges, and yellow discoloration
• B. Redness and swelling
• C. Thickening and splitting
• D. Discoloration and brittleness

Answer: (A)

Nail psoriasis is characterized by specific symptoms that reflect the underlying autoimmune condition affecting the nails. Pitting, which refers to small depressions on the nail surface, is a hallmark of nail psoriasis. These pits can vary in size and depth, contributing to an uneven nail texture. Ridges may also develop, presenting as vertical or horizontal lines that can run along the nail body. Furthermore, yellow discoloration of the nails can occur, often accompanied by a condition known as "oil drop" appearance, where a yellow spot can be seen beneath the nail.

The presence of these symptoms – pitting, ridges, and yellow discoloration – directly links to the pathological processes of psoriasis, making this choice correct. Other symptoms associated with nail disorders might show up in different conditions, but the combination of the highlighted symptoms distinctly points to nail psoriasis. Understanding these symptoms is crucial for accurate diagnosis and effective management of the condition.
