The specimen is a portion of a skin lesion; the lesion consists of coarse tufts of epithelium showing
a varying amount of pigment. The histology of the lesion is that of a compound naevus; the fronds
are covered by stratified squamous epithelium in the basal layer of which are nests of naevus cells;
the dermis contains numerous naevus cells. The lesion is benign.
This was an incidental finding and was removed for cosmetic reasons in an adolescent
with spina bifida.
