Vesicles - Overview

Alternative Names

Blisters

Definition of Vesicles:

A vesicle is a small fluid-filled blister.

Considerations:

A vesicle is small -- it may be as tiny as the top of a pin or up to 5 or 10 millimeters wide.

In many cases, vesicles break easily and release their fluid onto the skin. When this fluid dries, yellow crusts may remain on the skin surface.

Common Causes:

Many diseases and conditions can cause vesicles. Some common examples include:

Allergic reactions to drugs
Atopic dermatitis (eczema)
Blistering skin diseases including porphyria cutanea tarda and dermatitis herpetiformis
Chicken pox
Contact dermatitis (may be caused by poison ivy)
Herpes simplex (cold sores, genital herpes)
Herpes zoster (shingles)
