Shave Biopsy
A sampling technique where superficial tissue is removed with a tangential blade motion. Typically performed for raised lesions suspected to be benign.
Full Definition
A shave biopsy involves removing a superficial specimen using a scalpel blade held parallel to the skin surface in a tangential cutting motion. This technique is commonly employed for elevated benign-appearing lesions such as seborrheic keratoses or papillomas. The procedure creates a controlled superficial wound that heals by secondary intention, typically leaving minimal scarring. However, shave biopsies are contraindicated when melanoma is suspected due to the risk of transecting the lesion and compromising staging information.
