Pterygium of the Nail

Pterygium of the nail plate is a growth of skin on the sides of the nail, which can lead to its deformation and dysfunction. Pterygiums can be caused by a variety of reasons, including injury, infection, nail and skin diseases.

Pterygium can be caused by various factors such as injury, chemicals, infections and diseases. It can cause pain, discomfort and impaired nail function.

To treat pterygium, you must consult a dermatologist. Treatment may include surgical removal of the pterygium, the use of topical medications to reduce skin growth and improve nail function.

Pterygiums constitute a fairly large group of diseases that occur with the development of a pathological process in the area of ​​the base of the nail plate and the side of the affected finger adjacent to its base.

Pterygium as a separate diagnosis has only existed for a few decades. In 1926, at the University of Zurich, a student of Professor Conrad Niemeyer, M. Ludheimer, described a disease presumably associated with fungal infections of the periungual fold. The disease was characterized by erythema and the appearance of a dystrophic plaque in the periungual fold, disrupting the transparency of the nail. According to M.A. Lungaver, pterygian lesions are secondary, developing against the background of an existing lesion of the nail bed. The term pterygius was proposed by Holman in 1945. Many patients with pterygus have a question: where does this pathological lesion come from - a defect in the layer of the nail plate? It would seem that if we take into account the influence of mechanical load, alternating friction of the nail matrix on the bed, i.e. tension, an abnormality must occur in the cell matrix or keratin organelles. The likelihood of such an anomaly is extremely low, since the strength of the nail is relatively small and much more force is required to destroy it. And only in case of injury to the impact of mechanical factors, the strength of the nail sharply decreases and all the signs of pterygium appear. Then the appearance of a nail defect caused by mechanical action can be taken as the initial part. In a healthy person, as a result
