Chaos and clues algorithm for dermoscopy

Chaos and clues algorithm for dermoscopy

Illustration of the chaos and clues algorithm for the dermoscopic evaluation of pigmented skin lesions.

Chaos:
- Asymmetric distribution of dermoscopic structures or colors
Clues for malignancy:
- Eccentric, structureless area of any color, except skin color
- Thick lines, reticular or branched
- Gray or blue structures (ie, lines, circles, clods, and dots)
- Black dots or clods, located along peripheral edge
- Radial lines or pseudopods, segmental (or focal)
- White lines, including lines arranged perpendicularly to each other (only seen with polarized dermoscopy) and reticular, white lines (seen with both polarized and nonpolarized dermoscopy)
- Polymorphous vessels (more than one vessel morphology)
- Lines parallel, ridges (volar) or chaotic (nails)

* Any exception to chaos? If yes, perform a biopsy.
