Vesicle (dermatology)

Vesicle (dermatology)

A vesicle in dermatology refers to a small, fluid-filled blister on the surface of the skin. Vesicles are less than 5 millimeters in diameter and are often caused by various medical conditions, including herpes simplex, chickenpox, and contact dermatitis.

Causes

Vesicles can be caused by a variety of conditions. These include:

• Herpes simplex: This is a viral infection that often results in the formation of vesicles on the skin and mucous membranes.

• Chickenpox: This is a highly contagious disease caused by the varicella-zoster virus. It is characterized by the appearance of vesicles all over the body.

• Contact dermatitis: This is a skin reaction resulting from exposure to allergens or irritants. Vesicles can form as a result of the skin's reaction.

Symptoms

The primary symptom of a vesicle is the presence of small, fluid-filled blisters on the skin. These blisters can be painful or itchy. Other symptoms can include redness, swelling, and inflammation around the vesicle.

Treatment

Treatment for vesicles depends on the underlying cause. Antiviral medications are often used for vesicles caused by herpes simplex or chickenpox. For vesicles caused by contact dermatitis, treatment typically involves avoiding the allergen or irritant and using topical creams to relieve symptoms.
