Intradermal congenital-type nevus

Microscopic description

The sections show hair-bearing skin with epithelioid, dermal melanocytes, with occasional pigmentation, small or indistinct nucleoli and occasional nuclear inclusions, that are arranged in small nests. The lesional melanocytes are separated from the overlying epidermis in the plane of the sections and track along pilosebaceous units with deeper cuts. The epithelium matures normally to the surface. There is no inflammation or dysplasia.
