PY - 2020 T2 - Barnhill's Dermatopathology, 4e AB - An exceptionally diverse group of disorders that are both heterogeneous in their genetic or acquired pathophysiologic bases and pleiotropic in their phenotypic expressions can be assembled under the general category of alterations of the stratum corneum and epidermis. These disorders reflect a wide range of acquired and hereditary pathologic processes. Two distinct themes, however, unite many of the entities described here. One common pathophysiologic feature reflects defects in the cornification process that manifest clinicopathologically as ichthyoses; the other involves molecular defects in keratin genes and other genes yet to be determined that confer defective epidermal integrity and that present clinically as the mechanobullous disorders.
