Definition of dermoscopy patterns and demographics

Low-risk Dermoscopic Patterns
Parallel Furrow Linear pigmentation most prominent in the furrows.
Lattice-like Linear pigmentation following the furrows and linear bands of pigment crossing over the ridge to the next furrow.
Regular Fibrillar Thin, even, pigmentation tangential to furrows and ridges.

Indeterminate Dermoscopic Patterns
Reticular Regular reticulated pigment network.
Globular Regular globules not associated with a parallel furrow pattern.
Homogeneous Regular, diffuse pigmentation.
Non-typical Not fitting with a classic benign or malignant pattern.

High-risk Dermoscopic Patterns§
Parallel Ridge Linear pigmentation more prominent on the ridges of skin markings.
Multi-component Several dermoscopic patterns irregularly distributed throughout the lesion. (e.g: diffuse pigmentation, irregular dots and globules, irregular pigment network, atypical streaks, and multiple colors. Note that regions of benign patterns may be seen in the same lesion)

Demographics
Age Gender History of Skin Cancer

Mean SD Median Males 45 (37.2%) Non-melanoma 15 (12.4%)
51.7 16.2 52.0 Females 76 (62.8%) Melanoma 6 (5.0%)

Likely to be benign, recommended to not be biopsied regardless of size.13

Likely to be benign, however they should be biopsied if larger than 7mm.13
