Evaluation
A bright light and/or Woodโs lamp is very helpful in adequately assessing clinical tumor margins. Sidelighting as well as gently rubbing the lesion with an alcohol wipe and manipulating the skin are all helpful techniques.
Surrounding skin should be evaluated as well; this serves to both ensure that there is no local inflammation that may impede wound healing (seborrheic dermatitis, angular cheilitis, etc.) and to assess whether the postexcision defect will impinge on other preexisting nevi or other skin lesions. For example, a banal nevus that was just lateral to a newly excised dysplastic nevus may appear directly adjacent to the scar line postoperatively. This should be noted and reviewed with the patient so that a focal area of pigmentation adjacent to the scar line is not confused with recurrence.
Scars elsewhere on the patientโs body should be evaluated as well, if possible. This serves two purposes: first, it provides a baseline measure for the surgeon regarding the patientโs propensity to heal with hypertrophic or telangiectatic scarring. Second, it provides a reference point for patient education, so that the patient may be told what to expect in terms of healing relative to their existing scars. It may also be a significant motivator for encouraging adequate postoperative compliance.
