Vesicles


Definition:

A vesicle is a small fluid-filled blister.

Alternative Names:

Blisters

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.

Causes:

Many diseases and conditions can cause vesicles. Common examples include:

Home Care:

It is best to have your health care provider examine any skin rashes, including vesicles.

Over-the-counter treatments are available for certain conditions that cause vesicles, including poison ivy and cold sores.

When to contact a medical professional:

Call your doctor if you have any unexplained blisters on your skin.

What to Expect at Your Office Visit:

Your doctor will look at your skin. Some vesicules can be diagnosed simply by how they look.

In many cases, however, additional tests are needed. The fluid inside a blister may be sent to a lab for closer examination. In particularly difficult cases, a skin biopsy may be needed to make or confirm a diagnosis.
