Certain skin rashes are more than meets the eye. When the diagnosis is in question or review by a pathologist is warranted, a very small piece of skin and underlying dermis can be sampled in the office for review. This involves a local numbing anesthetic and a small piece of skin (less than the size of a pencil eraser) being taken, followed by a small stitch to enhance healing and reduce scarring. The suture or stitch can be removed generally one week later in the office when the patient returns for the biopsy results, or by the patient's primary physician.
