A skin biopsy is a simple, in-office procedure used to diagnose a variety of skin conditions by removing a small sample of skin for laboratory analysis. It is a key tool in detecting skin cancers, inflammatory conditions, and other dermatologic concerns with accuracy.
When a Skin Biopsy May Be Recommended
Your dermatologist may suggest a biopsy if you have:
- A suspicious mole or skin growth
- A rash or lesion that does not resolve with treatment
- A sore that does not heal
- Changes in skin color, texture, or thickness
- Symptoms suggesting autoimmune or inflammatory skin disease
Types of Skin Biopsies
- Shave Biopsy – Removes the outer layers of skin for surface-level analysis.
- Punch Biopsy – Uses a circular tool to remove a deeper core of skin, including the epidermis, dermis, and superficial fat.
- Excisional Biopsy – Surgically removes the entire lesion, often used for larger or high-risk growths.
What to Expect
- Preparation: The biopsy site is cleaned, and local anesthesia is applied to ensure a painless experience.
- Procedure: The appropriate biopsy method is performed based on the size, location, and nature of the skin concern.
- Aftercare: A bandage is applied, and you will receive detailed instructions to promote healing and reduce the risk of scarring or infection.
- Results: The sample is sent to a dermatopathology lab for microscopic examination, and results are typically available within 1–2 weeks.
