What does lentigo maligna melanoma look like on the face?

It should be highlighted that the aforementioned melanoma-specific structures can be seen in lentigo maligna melanomas on the face and also in lentigo maligna melanomas arising on nonfacial chronic sun-damaged skin. In this lentigo maligna melanoma the double circle (circle in circle) pattern is easy to see.

What are the dermoscopic features of melanoma?

The dermoscopic features are enormously variable. Early melanoma is relatively organised but as time progresses, it becomes more disorganised, and this is reflected by the dermoscopy. Melanomas have features indicating their melanocytic origin: Many other features have been described in melanoma. And they may be relatively featureless.
