ShaveBiopsie

Shave biopsy, also known as shave biopsy in English and ShaveBiopsie in German, is a minor dermatologic procedure used to obtain a tissue sample from a skin lesion for histopathological examination. The technique involves shaving off a thin layer of skin with a scalpel or razor blade, usually parallel to the skin surface, so that the epidermis and a portion of the dermis are removed. The specimen is then sent to pathology for diagnosis. The wound is typically shallow and heals with a small scar.

The procedure is performed under local anesthesia, usually lidocaine, to numb the area. The lesion is stabilized with forceps, and the clinician uses a blade to shave away the lesion, sometimes with a small amount of surrounding normal skin to ensure adequate tissue. Hemostasis is achieved by firm pressure and, if needed, cautery. The depth of the shave can vary, but it is generally limited to epidermal and superficial dermal tissue.

Indications include evaluation of raised or superficial lesions such as seborrheic keratoses, warts, actinic keratoses, sebaceous or vascular lesions, and certain pigmented lesions when shallow depth is sufficient for diagnosis. It is not ideal when deep margins are required or when melanoma or other invasive cancers are suspected, as full-thickness margins are often not obtained.

Advantages include speed, outpatient convenience, and generally favorable cosmetic outcomes for superficial lesions. Limitations include the potential for incomplete removal, limited assessment of lesion depth, and risk of scarring or pigment changes.

Post-procedure care typically involves keeping the area clean, applying a thin layer of antibiotic ointment, and covering with a dressing. Patients should monitor for infection, uncontrolled bleeding, and note any changes in the scar or pigment.
