In a 50-year-old man, on the hip
What to see at dermoscopy:
-globular pattern
-terminal hairs with perifollicular hypopigmentation
-structureless areas
-erythema
-milia-like cysts
Dermoscopy in favor of dermal nevus. Regular control was suggested
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 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 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 43-year-old man, on the back (years of evolution)
What to see at dermoscopy:
-erythema
-giant comedo-like openings (circle)
-giant milia-like cysts
-scaly surface
Dermoscopy in favor of Darier´s disease and histopathology confirmed the diagnosis.
Comments:variable vascular structures (red dots, red lines or erythema) associated with giant comedo-like openings were previous demonstrated as dermoscopic pattern in patients with Darier´s disease.
