]. In this paper, the term “micromelanoma” is coined to represent melanomas under 2 mm. The presentation is also unusual because of the age and clinical presentation of this lesion not being clinically different to the patient’s other nevi. Further this patient had <5 nevi overall.

What is the average size of a melanoma?

Melanomas are often larger than 6 mm (1/4 inch) in diameter. However, with increased awareness about early detection, about 30% of melanomas are found when they are less than 6 mm in diameter.
