<unk>  is a biopsy technique in which a<unk>  lesion is removed to be sent to a pathologist to render a microscopic diagnosis. It is usually done under local anesthetic in a physician's office, and results are often available in 4 to 10 days. It is commonly performed by dermatologists.<unk> es are also done by family physicians, internists, surgeons, and other specialties. However, performed incorrectly, and without appropriate clinical information, a pathologist's interpretation of a<unk>  can be severely limited, and therefore doctors and patients may forgo traditional biopsy techniques and instead choose Mohs surgery. There are four main types of<unk> es: shave biopsy, punch biopsy, excisional biopsy, and incisional biopsy. The choice of the different<unk> es is dependent on the suspected diagnosis of the<unk>  lesion. Like most biopsies, patient consent and anesthesia (usually lidocaine injected into the<unk>  are prerequisites.
