In a 46-year-old man, on the back
What to see at dermoscopy:
-Multicomponent pattern
-Blue-white veil
-Clustered dots at periphery (circle)
-Chrysalys structures (arrows)
-Scar-like depigmentation
-Telangectasia over the regression area
-Erythema
Dermoscopy in favor of Melanoma and histology confirmed the diagnosis.

In a 25-year-old woman, on the trunk;previous history of other nevi extirpation (including a dysplastic nevus)
What to see at dermoscopy:
-Multicomponent pattern
-Globules
-Irregular distributed dots
-Negative pigment network at the periphery of lesion
-Irregular blotches at central area
-Blue-white veil
-Perifollicular hypopigmentation
-Hypopigmented areas
Extirpation was suggested and histology correlation was: compound nevus
