Shave biopsy

A shave biopsy is a technique used to remove raised superficial lesions by shaving them level with or slightly below the surface of the surrounding skin. It is often used for benign growths and some low risk lesions on cosmetically sensitive areas.

When shave biopsy is used

Shave biopsy may be suitable for:

• Raised benign lesions such as some seborrhoeic keratoses
• Selected skin tags and small benign papules
• Certain lesions where a superficial sample is adequate for diagnosis

How the procedure is carried out

The area is cleaned and local anaesthetic is injected just under the lesion. A fine blade is then used to remove the raised part of the lesion. The wound surface is usually treated with cautery or a chemical to stop bleeding and create a thin crust.

The removed tissue is sent for histological examination if there is any diagnostic uncertainty.

Healing and possible outcomes

The site generally heals with a flat or slightly indented pale mark. In some cases, a small amount of the lesion may regrow, and further treatment may be considered.

• Short healing time compared with deeper excisions
• Low risk of complications when aftercare advice is followed
• Scarring is usually minimal, but varies between individuals
