Nail psoriasis is characterized by which of the following?

Nail psoriasis is primarily characterized by nail surface pitting and roughness. This condition manifests due to the rapid turnover of skin cells, leading to a build-up that creates small indentations and an uneven texture on the nail surface.

Understanding the nature of nail psoriasis is critical for identification and appropriate treatment. Individuals with this condition often notice that their nails have not only pitting but may also appear discolored or develop irregular shapes. Therefore, recognizing the significance of nail surface pitting is essential for those studying nail theory, as it aids in differentiating psoriasis from other nail disorders.

The presence of brittle nails, visible depressions across the nail, or dark spots from injury are signs associated with other conditions. Brittle nails can indicate nutritional deficiencies or other health issues, whereas visible depressions may be linked with other nail pathologies. Dark spots often suggest trauma rather than a dermatological disorder like psoriasis. Understanding these differences is crucial for anyone practicing within the field of nail care and treatment.
