In a 23-year-old man, on the back
What to see at dermoscopy:
-blue-red to blue-black lacunae
-blue-white veil
-red halo of erythema
Dermoscopy in favor of vascular lesion. The confluent blue-black pigmentation sharply demarcated at the periphery suggests partially thrombosed lesion.Such lesions can sometimes be confused with nodular melanoma. Short follow-up was recommended
In a 15-year-old woman, on the abdomen
What to see at dermoscopy:
-regular globular pattern
-irregular blue-white veil distribution
Dermoscopy in favor of dermal nevus. Regular control was suggested
In a 67-year-old men, on the chest
What to see at dermoscopy:
-blue-gray ovoid nests and blue-gray globules
-structureless areas (erythema)
-fine and arboriform telangectasias
-ulceration
-blue-white veil
Dermoscopy in favor of basal cell carcinoma and histology confirmed diagnosis
In a 64-year-old man, on the thigh
What to see at dermoscopy:
-reticulo-globular pattern
-perifollicular hypopigmentation
-blue-white veil
-terminal hair
Dermoscopy in favor of congenital nevus. Regular follow-up was indicated.
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
