Skin biopsy is a medical procedure where a small piece of skin is removed from the body for examination under a microscope. The purpose of this procedure is to diagnose or evaluate a skin condition, such as a rash, lesion, or mole. Skin biopsy can help identify the cause of a skin problem, such as infection, inflammation, or cancer. In this article, we will discuss the different types of skin biopsy, how they are performed, and what to expect during and after the procedure.
Types of Skin Biopsy
There are three main types of skin biopsy: punch biopsy, shave biopsy, and excisional biopsy. The choice of biopsy depends on the size and location of the skin lesion, as well as the suspected diagnosis.
- Punch biopsy: This is the most common type of skin biopsy. A punch tool is used to remove a small cylinder-shaped sample of skin from the surface and deeper layers of the skin. Punch biopsy is usually performed to diagnose skin conditions such as infections, rashes, and non-melanoma skin cancer.
- Shave biopsy: This type of biopsy involves removing a thin slice of skin from the top layer using a sharp blade. It is commonly used to remove small, benign skin growths, such as moles or warts.
- Excisional biopsy: This type of biopsy involves removing the entire lesion, including some of the surrounding tissue. It is usually performed when a lesion is suspected to be cancerous.
How is Skin Biopsy Performed?
Skin biopsy is usually an outpatient procedure that can be performed in a dermatologist’s office or a hospital. Before the procedure, the patient’s skin is cleaned and numbed with a local anesthetic. The biopsy tool is then used to remove the skin sample. After the biopsy, the area is cleaned and covered with a bandage.
What to Expect During and After Skin Biopsy?
During the procedure, patients may feel a slight pinch or pressure when the biopsy tool is applied. However, the local anesthesia should minimize any discomfort. After the procedure, the biopsy site may be tender or sore for a few days. Patients should avoid strenuous activities and keep the biopsy site clean and dry to prevent infection. Results of the biopsy may take several days to a week to be available.

Result or interpretation
The normal range for skin biopsy depends on the specific condition being evaluated. However, a pathologist can evaluate the biopsy sample and provide a diagnosis. The diagnosis will determine if the biopsy results are within normal limits.
