In a 57-year-old woman, on the back
What to see at dermoscopy:
-multicomponent pattern
-atypical pigment network
-negative pigment network
-regression areas (scar-like depigmentation)
-structureless areas
-hypopigmented areas
-vascular polymorphism
-erythema
Extirpation was indicated. Dermoscopy in favor of melanoma.
In a 63-year-old man, on the back
What to see at dermoscopy:
-multicomponent pattern
-atypical pigment network
-negative pigment network (circle)
-regression area (scar-like depigmentaton) [arrow]
-structureless areas
-hypopigmented areas
Dermoscopy in favor of melanoma and histopathology confirmed the diagnosis.
In a 15-year-old boy, on the back (multiple similar lesions)
What to see at dermoscopy:
-multicomponent pattern
-pigment network
-globules
-strutureless areas
-erythema
Dermoscopy in favor of dysplastic nevus. The presence of other similarly lesions (by dermoscopy) consists in predominant nevus pattern. Control was indicated
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
