Chloronychia

Elaphe mandarina

Green nail syndrome (GNS), also known as Chromonychia, is a nail disorder characterized by greenish discoloration of the nails. It is often caused by a bacterial infection, specifically by the bacteria Pseudomonas aeruginosa.

Causes

The primary cause of green nail syndrome is infection with the bacteria Pseudomonas aeruginosa. This bacteria is commonly found in the environment and can enter the body through a break in the skin or nail. The bacteria produce a green pigment called pyocyanin, which is responsible for the green discoloration of the nails.

Symptoms

The main symptom of green nail syndrome is a greenish discoloration of the nails. Other symptoms may include:

• Nail discoloration (usually green, but can also be black or blue)
• Nail thickening
• Nail crumbling
• Nail detachment

Diagnosis

Diagnosis of green nail syndrome is typically based on the characteristic green discoloration of the nails. A doctor may also take a nail sample to confirm the presence of Pseudomonas aeruginosa.

Treatment

Treatment for green nail syndrome usually involves topical or oral antibiotics to eliminate the Pseudomonas aeruginosa infection. In severe cases, the affected nail may need to be removed.

Prevention

Prevention of green nail syndrome involves good nail hygiene, such as keeping the nails clean and dry, and avoiding nail trauma.
