Central scar-like white patch with delicate surrounding network-like structures[edit]

Central scar-like white patch: irregularly outlined and sharply-demarcated white area in lesion center. On nonpolarize dermoscopy, appears as a white scar-like area; on polarized dermoscopy, appears as a bright white areas +/- shiny white lines.
Delicate pigment network: light-to-medium brown pigment network with a fine/delicate quality; gradually fades into surrounding skin; usually located at periphery of lesion.[1]

Ring-like globules[edit]

The pigment network located toward the center of the lesion often ceases to look like a reticulated mesh but rather begins to resemble “ring-like” globular structures.[2]

Central shiny white lines (crystalline structures)[edit]

Irregularly outlined and sharply-demarcated white area in lesion center. On nonpolarized dermoscopy, this appears as a white scar-like area; on polarized dermoscopy, it appears as a bright white areas with or without shiny white lines.[3]
