Figure 1.

Close view-up of the skin in two children with cutis tricolor: as a pure trait (A) in an archetypical sash-like (spiral) pattern of mosaic distribution [case 2 in (3)]; and (B) as a complex malformation phenotype in a less-well defined/unclassifiable mosaic pattern of distribution [case 1 in (3)]. Note the hyperpigmented (the “hyperpigmentation” is pointed by the black arrows) and hypopigmented (the “hypopigmentation” is pointed by the white arrows) areas in close proximity one to each other in a background of normal complexion (labelled as “normal”).
