Prurigo simplex

Prurigo simplex is a skin condition characterized by the presence of small, itchy bumps on the skin. It is a chronic condition that can persist for many years, and is often associated with other skin conditions such as atopic dermatitis and urticaria. The exact cause of prurigo simplex is unknown, but it is thought to be related to an overactive immune response to a variety of triggers.

Symptoms

The primary symptom of prurigo simplex is the presence of small, itchy bumps on the skin. These bumps are typically less than 1 cm in diameter and are often covered by a crust. The bumps can appear anywhere on the body, but are most commonly found on the arms, legs, and trunk. Other symptoms can include redness, swelling, and a burning sensation at the site of the bumps.

Causes

The exact cause of prurigo simplex is unknown, but it is thought to be related to an overactive immune response. This can be triggered by a variety of factors, including:

• Insect bites
• Allergies
• Infections
• Stress
• Exposure to certain chemicals
• Certain medications

Diagnosis

Diagnosis of prurigo simplex is typically based on the appearance of the skin and the presence of itching. A skin biopsy may be performed to rule out other conditions.

Treatment

Treatment for prurigo simplex is aimed at relieving the symptoms and preventing new bumps from forming. This can include:

• Topical corticosteroids
• Antihistamines
• Phototherapy
