Nail psoriasis symptoms

Nail psoriasis is a disease with long history. It was described back in the XIX century, and the difficulty of its diagnosing was also mentioned. Scientists assumed that the disease has an isolated form. Nowadays this hypothesis was confirmed. Psoriasis of the nails can develop independently. But very often when patients have any form of psoriasis nails also may become affected. There are many nail psoriasis symptoms.

Clinical presentations of the disease are very diverse. The most common are the following types of nail plate deformation: little pits on the nails (called “thimble symptom”), subungual hemorrhage, onycholysis, trachyonychia. Let us have a look on them in more detail.

Thimble symptom

This is the most well-known form of nail psoriasis. It manifests itself in the form of small pits of various diameters (0.5-2 mm) on the nail plate. The cause of psoriasis in nails lies in the nail plate formation malfunction. The pits are different in shape, size and depth and are located chaotically, resembling the surface of a thimble. Normally, a healthy person may have isolated pits on nails, but this is not considered to be psoriatic nails. Such nail plate changes can also accompany other chronic dermatoses.

Onycholysis

This is the second common symptom of psoriasis on nails. Nail plate separates from its bed gradually and without any pain. It is not accompanied with inflammatory processes. Loosening usually starts on top of the nail plate and spreads towards the root. There are two degrees of manifestation of psoriasis under nails: full and partial.

When nails loosen an empty space is formed underneath the nail plate. Dust, dirt and air bubbles easily get into this hollowness. In it there is also exfoliated epidermis, which makes the nail look grayish-white. Sometimes the colour can vary from yellow to brown. In some cases, onycholysis may be accompanied by an unpleasant odor. A distinctive feature of this form is the presence of a narrow pinkish stripe, which eventually becomes yellowish.

Subungual hemorrhage

There are two types of subungual hemorrhage that have different characteristics. The first is characterized by the appearance of spots under the nail plate. The spots can vary in size and are pink or bright red. The disease is also known as the “syndrome of oil spots”. The second type of subungual hemorrhage appears as strip bleeding of red, brown and sometimes black colour. This type is a result of rupture of blood capillaries.

Trachyonychia

Sometimes it accompanies psoriasis vulgaris. Trachyonychia is characterized by dull and rough surface of the nail. As a rule, there is no lunula. In some cases, this pathology is accompanied by the indentation in the center of the nail plate. At the early stages of psoriatic nail disease can be observed flattening of the nail, which later becomes concave. Subungual tissue is not prone to changes.
