A British-developed diagnostic aid that relies on four major and three minor criteria. It also relies heavily on
the concept of evolution (i.e., change). In fact, the three major criteria are historical (change in size, shape, and color), while the four minor are instead physical and often late-appearing: (1) inflammation, (2) crusting or bleeding, (3) sensory change, and (4) diameter >7 mm.
A scoring system assigns two points for each major criterion and one for each minor. Patients with
>1 major criterion should be referred to a dermatologist. Patients with scores >3 should be referred, too.
