Surgical Skin Biopsy

Overview

This procedure takes a sample of skin from your body. We do this to study skin cells for signs of disease. We also use it to remove suspicious growths. There are three main types of skin biopsies. Let's look at each one.

Shave biopsy

The first method is called a "shave biopsy." We do this when we need to study a growth on the outermost layer of skin. We use a scalpel or cutting device to slice off a thin layer of the abnormal tissue. Your skin is bandaged, and a scab forms as it heals.

Punch biopsy

The next method is called a "punch biopsy." It lets us sample the outermost and the deeper layers of skin. We use a cutting device that has a circular blade. It punches down through the skin and takes a round core of tissue. Then, we close the skin with sutures and a bandage.

Excisional biopsy

The final method is called an "excisional biopsy." We do this when we need to remove a growth or a larger area of tissue. We use a scalpel to remove the skin and deeper tissue. Then, we close the skin with sutures and a bandage.

Conclusion

After your biopsy, we send the tissue to a lab for study. Your doctor will follow up with the results and a care plan that's right for you.
