Female, 49 years. Greyish nodule, skin of back
The first low-power impression is of a combined naevus, with central deep penetrating naevus component, though rather a bulky and cellular one. The cells are rounded and atypical, not very pleomorphic, but feature quite atypical nuclei, and form closely apposed small groups and nodules with high mitotic activity. This constellation of findings was regarded as indicative of malignancy.
