Flowchart for the Prediction without Pigment algorithm. End-points colored red are highly suspicious for malignancy, while those colored green should be benign. All other endpoints should be assessed by weighing all clues, both clinical and dermatoscopic, as there are malignant options in the differential diagnosis. The diagnoses listed are not exhaustive but are selected to guide the decision process. It may be useful to have this flowchart open when looking at the lesions depicted in Figures 4–10.
