Mildly dysplastic nevus

[color=#000000][b]Dysplas[b]tic[/b] naevus. Bridging nests with mild cytological atypia [/b](the nuclei equal the nuclei of the overlying keratinocytes in size, hyperchromatic nuclei, with prominent nucleoli), [b]stromal response[/b] (increased collagen, superficial lymphoid cells infiltrate). When there is a junctional component that is symmetrically distributed at the junctional edges that extend laterally beyond a central dermal component this forms clinically the fried egg pattern (macular component surrounding a papular centre) and histopathologically the shoulder phenomenon (not in the example shown). [/color][color=#000000]It has been said that junctional and compound [/color][color=#0A0905]dysplastic naevi form, clinically and histopathologically, a continuum extending from a common naevus to a superficial spreading melanoma.

Dysplastic nevus is correct. Isn't it a beautiful example?

It is a beautiful example indeed.
