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 55-year-old woman, on the shoulder
What to see at dermoscopy:
-lesion greater than 5 mm
-atypical reticular pattern (some areas with broadened pigment network)
-globules (rares)
-hypopigmented areas
-structureless area
Extirpation was indicated. Histopathology correlation was: lentiginous junctional nevus
In a 37-year-old man, on the trunk (3 different lesions)
What to see at dermoscopy:
-reticulo-globular pattern
-central hypopigmented area
Dermoscopy in favor of compound nevus. Regular control was suggested.
Comments: although every lesion showed a irregular pigment network the presence of constant dermoscopic features consists in predominant nevus pattern.
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
