When a spot, rash, or growth doesn’t look quite right, uncertainty can be stressful. A skin biopsy helps provide clear answers so the right treatment plan can begin.
A skin biopsy is a simple, in-office procedure that allows your dermatologist to examine a small sample of skin under a microscope. This page explains why biopsies are done, the different types, what to expect, and how to care for the area afterward.
At ProDerm Skin & Surgery in Austin, skin biopsies are performed by Dr. Sydney Larkin Proffer, a board-certified dermatologist with advanced fellowship training in micrographic surgery and dermato-oncology.
What Is a Skin Biopsy?
A skin biopsy involves removing a small piece of skin so it can be examined by a laboratory. The results help diagnose a wide range of skin conditions.
Biopsies are commonly used to evaluate suspicious moles, rashes, sores that won’t heal, and potential skin cancers.
Why Your Dermatologist May Recommend a Biopsy
- A new or changing mole or growth
- A lesion with irregular color, border, or shape
- A rash that does not improve with treatment
- A sore that bleeds or fails to heal
- A scaly or rough patch that may be precancerous
Types of Skin Biopsies
The biopsy method depends on the location and suspected diagnosis.
- Shave biopsy: Removes the top layers of skin, often used for raised lesions
- Punch biopsy: Uses a small circular tool to remove a deeper sample
- Excisional biopsy: Removes the entire lesion and typically requires stitches
What to Expect During the Procedure
Skin biopsies are performed in the office and usually take only a few minutes. The area is cleaned and numbed with local anesthesia.
You may feel pressure but should not feel pain. After the sample is taken, the site is treated and bandaged.
Healing, Aftercare, and Results
Most biopsy sites heal within one to two weeks, depending on depth and location.
- Keep the area clean and moist with ointment
- Change bandages as instructed
- Avoid swimming or soaking until healed
- Protect the area from sun exposure
Results are typically available within several days to two weeks. Your care team will review the findings and discuss next steps.
