A 52-year-old woman consulted for a pigmented lesion of her nose. This lesion was biopsied and pathology revealed an actinic keratosis.
The dermoscopic feature was a pseudonetwork.The dilated follicular openings seen on the facial skin create a false broadened network or pseudonetwork that can be observed in various benign pigmented lesions as ephelide (freckle), actinic lentigo, actinic keratosis and junctional nevus.
