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 50-year-old man, on the thigh
What to see at dermoscopy:
-reticulo-globular pattern
-irregularly distributed dots (circle)
-blue-white veil that covers all lesion
Dermoscopy in favor of dermal nevi and histopathology confirmed the diagnosis
Comments: The presence of irregular dots justified extirpation
to rule out a melanoma arising from melanocytic nevi
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
In a 35-year-old man, on the neck (intense photodamaged skin)
What to see at dermoscopy:
- asymmetry of color and shape
- multicomponent pattern
- pigment network and globules
- negative network
- blotches
-chrysalis structures
-milia-like cysts
Extirpation was suggested
Histopathological correlation: compound nevi
Comments: the presence of negative network is often seen in melanoma but is an infrequent dermoscopic finding in benign lesions (Spitz and congenital nevi) where it is usually symmetric and central.
In a 9-year-old girl, on the upper lip (lesion present since early years of life)
What to see at dermoscopy:
-asymmetry of color and shape
-delicate pigment network in the lower portion of lesion (parallel-like pattern)
-irregular globular pattern
-blotches
-blue-white veil
Biopsy was suggested
Histopathological correlation: compound nevi
Comments: after 2 years of regular follow-up, subtle changes were observed in this lesion therefore biopsy was indicated. Regular follow up was suggested.
