Hypertrophic actinic keratosis. A common hypertrophic variant of actinic keratosis is presented. Bland cytologic features are dominant, and the pattern varies markedly from that of other actinic keratoses. Histologic and topographic evidence suggests that the hypertrophic changes are induced by the trauma of chronic rubbing.
The typical actinic keratosis (AK) is a dry, scaly, rough bump that is skin-colored to reddish brown. The lesion may range from the size of a pinhead to larger than a quarter. Some skin colored AKs may be easier to feel than see. When touched, these often feel like sandpaper.
