- Nail psoriasis - a difficult problem
Nail psoriasis can be a sole manifestation of psoriasis, as well as to develop on the background of other forms of the disease. The difficulty of diagnosis and treatment of nail psoriasis

Causes of nail psoriasis
Reasons nail psoriasis, as well as other forms of psoriasis is not fully understood. The disease is considered an autoimmune, that is with him for some reason disrupted immune system, it does not recognize its own cells and tissues, and contributes to their destruction. It is believed that the causes of such disorders of the immune system are associated with genetic (family) characteristics of the organism.
Nail psoriasis provokes metabolic disorders

amid hypovitaminosis lack of macro- and microelements, neuroendocrine disorders, acute and chronic bacterial and viral infections, intoxications, reducing cleaning ability of the liver and so on. Provoke the development of nail psoriasis may also be injured.
The defeat of nail psoriasis can be for many years the only appearance of the disease. But it also happens that nail involvement is a complication of another form of psoriasis or vice versa, its first manifestation.
At the same time, together with a skin rash on the trunk, limbs and scalp (or independent of them) in some patients with psoriasis appear changes in the nail plate. These changes may be of a different character. So, nail psoriasis can manifest as a symptom of a thimble - the most typical violations of the nail plate.
Thus on the surface of the nail there are fine dots of deepening 0, 5-2 mm in diameter, as in a thimble. These depressions are the result of violations of the formation of the nail plate. These multiple recesses, but differ from each other in shape, size and depth. On different nail plate can be a different number of recesses.
Localized such grooves on the nails randomly one or two or in groups, often along longitudinal lines, but sometimes in another, while maintaining a certain order. One or two depressions on the nail often regarded as a normal variant.
Similar changes can occur on the nails and other skin diseases (eczema, lichen planus, and so on). Sometimes to distinguish one disease from another is problematic. However, it is noted that in psoriasis deepening more ordered and deep. They are also more painful when pressed with a sharp object (eg, a needle). In the form of a thimble symptoms often manifest nail psoriasis on the hands, but it is quite possible the emergence and legs.
Nail psoriasis can also occur oniholizisa - gradual painless separation of the nail plate from the nail bed without prior injury and inflammation in the area. Branch nail usually begins with a free edge (distal onycholysis), but sometimes from the root or from the side (central and lateral onycholysis). Branch nail can be complete or partial (full or partial onycholysis).
Branch nail can start up with raised edge of the nail plate or appearance of the nail in the separation of lines, shapes and so on. While gradually increasing the subungual area, wherein the deposited dust, dead cells of the epidermis, the air bubbles. All these changes are reflected in the appearance of the nail: it becomes grayish-white or brownish. A thin pink stripes on the surface of the nail (eventually it turns yellow) outlines oniholizisa zone. In some cases, the process oniholizisa accompanied by heavy smell of decay of tissues.
During oniholizisa may develop metabolic and degenerative changes at the base of the nail - onihomadeza. Onycholysis when it is more severe, and the rejection of the nail is faster than usual.
Psoriasis toenails often manifests itself in the form of subungual hemorrhage (bleeding). Meets this type of violations and on the hands. This symptom often occurs when wearing tight shoes. It is manifested in the form of a pink-red spots irregularly shaped, of different sizes, transmission through the nail plate. Such violations are also called "oil stains" or psoriatic hyponychial erythema. Sometimes, through the thickness of the nail shine dots or lines of dark red color, which after some time become black.
Another symptom of nail psoriasis - trahionihiya. It is characterized by the appearance of this symptom roughness and a turbidity of the nail plate. If the center appears traheonihii wide groove (in the center of the nail as it is pushed inside), it is called koilonychia. During the formation of the nail plate koilonychia first flattened, then the peripheral portion of the nail is bent upward, the center goes down and it gets spoon-shape, holding on the surface of the liquid drop (special test).
Sometimes nail psoriasis manifests as psoriasis paronychia - thickening and inflammation of the periungual roller, which then passes on all the final phalanx and even entire finger with the formation of pus. This symptom usually develops in severe forms of psoriasis - pustular psoriasis

or erythrodermic psoriasis. But sometimes psoriatic paronychia develops and non-severe forms of psoriasis.
