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.
Pathophysiology. Keratosis pilaris (KP) is a genetically based disorder of hyperkeratinization of the skin. An excess formation and/or buildup of keratin is thought to cause the abrasive goose-bump texture of the skin. In these patients, the process of keratinization (the formation of epidermal skin) is faulty.eratosis pilaris (KP) is a genetically based disorder of hyperkeratinization of the skin.
