Haemangiomas

 

These vascular lesions are benign proliferations of blood vessels. Dermoscopically they show round lacunes (or lakes) of homogenous red/blue pigment.

Angiokeratomas

 

Solitary angiokeratomas are acquired vascular lesions. They often present with dark lacunae often with a white veil and scale.

 

 

Pyogenic granulomas

 

These lesions often appear on the fingers after trauma or other stimuli (including drugs). These rapidly growing vascular proliferations have some common dermoscopic features. These include a pinky/white homogenous area surrounded by a white collarette of scale (collar).
