The sections show well-circumscribed dermal nests of basaloid cells with peripheral palisading, | |||
surrounded by a dense fibrous stroma. The basaloid cells have distinct nucleoli. Focally, the | |||
basaloid nests contain small clusters of cells with abundant pale, vacuolated, fluffy-appearing | |||
cytoplasm (sebocytes). Mitotic activity is minimal. | |||
There is no artefactual clefting between the stroma and basaloid cell nests. The epidermis | |||
matures to the surface and does not have basal atypia. | |||
The lesion is completely excised in the plane of section. | |||
