16.configuration: annular: circular, begins in center and spreads to
periphery
17.configuration: confluent: lesions run together
18.configuration: grouped: lesion cluster

20.configuration: linear: scratch, streak, line stripe
21.configuration: polycyclic: annular lesions merge
22.configuration: solitary or discrete: individual and distinct lesions that
remain separate
23.configuration: target (iris): resembles iris of eye; lesion with
concentric rings of color
