Scratch dermatitis
Scratch Dermatitis
Scratch dermatitis (pronunciation: /ˈskrætʃ dɜːrməˈtaɪtɪs/) is a type of skin condition that is characterized by inflammation and itching, often as a result of scratching.
Etymology
The term "scratch dermatitis" is derived from the English word "scratch," which refers to the act of scraping or rubbing a surface, often with one's nails, and the Greek word "dermatitis," which means inflammation of the skin.
Definition
Scratch dermatitis is a condition where the skin becomes inflamed and itchy due to excessive scratching. This can occur as a result of various underlying conditions such as eczema, psoriasis, or allergic reactions. The constant scratching can lead to the skin becoming red, swollen, and sometimes broken, which can further lead to potential infections.
Symptoms
The primary symptom of scratch dermatitis is an intense itch that leads to scratching. Other symptoms can include redness, swelling, and sometimes broken skin. In severe cases, there may be signs of infection such as pus, warmth, and tenderness.
Causes
Scratch dermatitis can be caused by a variety of factors. These can include:
- Allergies: Certain substances such as detergents, soaps, or certain types of fabric can cause an allergic reaction leading to itchiness and scratching.
- Skin conditions: Conditions such as eczema or psoriasis can cause itchiness and scratching.
- Insect bites: Bites from insects such as mosquitoes or fleas can cause itchiness and scratching.
Treatment
Treatment for scratch dermatitis primarily involves addressing the underlying cause of the itchiness and scratching. This can involve the use of topical creams or ointments, antihistamines, or in severe cases, corticosteroids. It is also important to keep the skin moisturized and to avoid scratching as much as possible.
