Pterygium colli

Pterygium Colli, also known as Webbed Neck, is a medical condition characterized by a web-like skin fold extending from the sides of the neck down to the shoulders. It is often associated with certain genetic disorders, most notably Turner Syndrome.

Symptoms and Signs

The primary symptom of Pterygium Colli is the presence of a web-like skin fold extending from the sides of the neck down to the shoulders. This can vary in severity from a mild skin fold to a more pronounced webbing that can restrict neck movement. Other symptoms can include a low hairline and a short neck.

Causes

Pterygium Colli is often associated with certain genetic disorders. The most common of these is Turner Syndrome, a condition that affects only females and is characterized by the partial or complete absence of one of the two X chromosomes. Other conditions that can be associated with Pterygium Colli include Noonan Syndrome and Cardiofaciocutaneous Syndrome.

Diagnosis

Diagnosis of Pterygium Colli is typically made through a physical examination. In cases where the condition is associated with a genetic disorder, genetic testing may be used to confirm the diagnosis.

Treatment

Treatment for Pterygium Colli is typically surgical and aims to improve the appearance and functionality of the neck. This can involve removing the excess skin and reconstructing the neck to a more normal appearance.
