What Is Skin Lesion Aspiration?
Skin lesion aspiration is a technique used by dermatologists to diagnose and treat an array of skin conditions. During the procedure, a dermatologist may use a fine needle to draw a small amount of fluid from an abnormality on the skin, such as a cyst or a blister. The fluid, called aspirate, will be examined under a microscope or sent to a lab for additional testing. The results of the tests will help the dermatologist determine the cause of the skin lesion and come up with a plan of treatment.
Preparation
Before the procedure, it’s important to talk to your doctor about your medical history and any medications you are taking. A physical exam will be done to assess the lesion and the area surrounding it. To minimize discomfort during the procedure, the doctor may use a topical anesthetic. It is important to wear loose, comfortable clothing so that the area of the skin lesion can be easily accessed.
Procedure
The procedure begins with the dermatologist inserting a fine needle into the lesion. The physician will draw a small sample of the aspirate, which will be placed in a sterile container. Once the sample is collected, the dermatologist may use a swab or patch to stop any bleeding. The sample will then be sent to a lab or examined under the microscope to determine the cause of the skin lesion.
Types of Aspiration
In addition to skin lesion aspiration, there are other types of aspiration that can be used to diagnose and treat various conditions. These include:
- Thoracentesis: A procedure used to remove and analyze fluid from the chest.
- Arthrocentesis: A procedure used to determine and treat the cause of joint pain.
- Paracentesis: A procedure used to remove excess fluid from the abdomen.
Risks
Generally, skin lesion aspiration is a safe procedure, but it may cause temporary pain or discomfort. In rare cases, an infection may occur. If you experience any unusual symptoms after the procedure, contact your doctor right away.
Why Skin Lesion Aspiration is Performed
Skin lesion aspiration is a useful tool for diagnosing and treating certain skin conditions. The procedure can be used to learn the cause of an abnormality on the skin, as well as to determine a plan of treatment. Skin lesion aspiration can also be used to sample a lesion to make sure it is benign (not cancerous).
When to Get Skin Lesion Aspiration
A skin lesion aspiration may be recommended if you have a lump, cyst, or other abnormality on your skin. The procedure can help to diagnose and treat the cause of the issue. Your doctor may also recommend skin lesion aspiration if you have had a biopsy or have been exposed to streaks of unidentified skin rash.
