Incisional biopsy

An incisional biopsy involves removing a portion of a lesion rather than the entire lesion. It is used when the area is large, located in a challenging site or when sampling a representative part is sufficient for diagnosis.

When an incisional biopsy is considered

Incisional biopsy may be recommended for:

• Large or poorly defined lesions
• Areas where complete removal at first stage would be difficult or disfiguring
• Rashes or plaques where a deeper or broader sample is needed

The procedure

Local anaesthetic is used to numb the area. The dermatologist removes a carefully selected segment of the lesion using a scalpel. The wound is then closed with stitches and the specimen is sent to the pathology laboratory for analysis.

Once a diagnosis has been confirmed, a treatment plan is made, which may include complete excision, medical therapy or regular monitoring.

Risks and healing

As with other minor procedures, incisional biopsy carries a small risk of bleeding, infection and scarring. Careful wound care and follow up help to minimise complications and optimise the cosmetic outcome.
