A skin biopsy is a technique in which a lesion is removed and sent to a pathologist to render a microscopic diagnosis. There are four main types of skin biopsies: shave biopsy, punch biopsy, excisional biopsy and incisional biopsy. The choice of skin biopsy technique is dependent on several factors including size, location and the suspected diagnosis. If needed, our physicians will perform the required biopsy to aid in the diagnosis and treatment of your specific skin condition.
