Which symptoms are typically associated with nail psoriasis?

Nail psoriasis is characterized by specific symptoms that directly correspond to the health and appearance of the nails themselves. The most commonly observed signs include pitting, ridges, and variations in color and texture of the nails.

Pitting refers to the small, shallow indentations that form on the surface of the nails, while ridges can appear as either vertical or horizontal lines. Changes in color can manifest as yellow, brown, or even a cloudy appearance, indicating the underlying inflammation and nail bed disturbances associated with psoriasis. Texture changes may include thickening or crumbling of the nail, which are also indicative of the condition.

Other options pertain to different conditions or symptoms not specific to nail psoriasis. For instance, dryness and cracking of the skin mainly relate to conditions affecting skin health rather than nail disorders. Excessive nail growth can occur for various reasons, but it is not a defining symptom of psoriasis, and the presence of green discoloration and odor typically suggests a bacterial infection rather than psoriasis. Thus, the symptoms associated with nail psoriasis are specifically identified by pitting, ridges, and changes in nail color and texture.
