Skin Biopsy

What is a Skin Biopsy?

A skin biopsy involves removing a small sample of skin tissue for examination under a microscope. This procedure allows dermatologists to diagnose and understand skin issues at a cellular level.

Metropolis Dermatology offers two main types of skin biopsies:

• Skin Shave Biopsy. A technique that removes the outer layer of skin, often used for lesions on the skin’s surface.
• Skin Punch Biopsy. This procedure goes deeper, using a small, round tool to remove a cylinder of skin, which includes multiple layers. It is especially useful for diagnosing conditions below the skin surface.

How Does a Skin Biopsy Work?

• Preparation. The skin area is cleaned and often numbed with a local anesthetic to ensure patient comfort.
• Removal. Depending on the lesion type, our provider will perform either a shave or punch biopsy, carefully removing a small portion of the affected skin.
• Processing. The sample is sent to a lab, where it is examined under a microscope for detailed analysis.
• Results. Our provider will review the findings and discuss any next steps, depending on the results.

Each step is performed with precision and care, aiming for minimal discomfort and maximum clarity in diagnosing the skin issue.

Why is a Skin Biopsy Important?

Skin biopsies offer several critical benefits:

• Early Detection of Skin Cancer. Biopsies can identify cancerous cells, allowing for early intervention.
• Accurate Diagnosis. It helps distinguish between various skin conditions, including infections, inflammatory diseases, and other dermatological issues.
• Targeted Treatment. With a confirmed diagnosis, our provider can create a tailored treatment plan.
• Monitoring Skin Conditions. For chronic skin diseases, biopsies help track progress or changes, ensuring treatment remains effective.
• Assessing Mole Changes. Biopsies are often performed on moles that have changed in size, color, or shape to rule out melanoma.
