Psoriatic Nails

Psoriatic nail disease is a common condition associated with psoriasis, affecting both fingernails and toenails. It occurs due to inflammation in the nail matrix and bed, leading to significant cosmetic and functional changes. Characteristic features include pitting, where small depressions form on the nail surface, and discoloration, ranging from yellow-brown patches to oil-drop appearances beneath the nail plate. Thickening of nails, often due to subungual hyperkeratosis, can make trimming and daily activities difficult.

In addition, patients may experience nail brittleness, crumbling, separation of the nail from the nail bed (onycholysis), or ridging that impacts nail texture. Psoriatic nails are often mistaken for fungal infections, as both can present with similar nail changes. Diagnosis typically involves clinical evaluation, sometimes supported by investigations like dermoscopy or laboratory tests to rule out fungal involvement.

Treatment focuses on controlling underlying psoriasis and minimizing nail symptoms. Options include topical corticosteroids, vitamin D analogs, systemic therapies such as methotrexate or biologics, and laser treatments in resistant cases. Regular nail care, moisturization, and avoiding trauma help reduce complications. Early recognition and management of psoriatic nails are essential, as they not only affect appearance but also impact a person’s quality of life.
