Dermoscopy of Atypical Nevi Structural Component Definitions

Reticular type: The reticular type is the most common pattern and is characterized by a pigment network with thin uniform lines and regular meshes. The pigment network is usually evenly distributed throughout the lesion and fades at the periphery.

Globular type: The globular type is characterized by dots and globules of variable size and shape (oval, round or rectangular) more or less evenly distributed throughout the lesion. The combination of the globular and reticular types is common. A common presentation of this combined pattern is a lesion with dots/globules located at the periphery an a regular reticulated pattern in the center.

Homogeneous types: The homogeneous pattern is the least common. There is diffuse pigmentation of various shades of brown and white with isolated reticular and/or globular areas.
