Skin: keratinization disorders

icanis

Synonym(s): Seborrhea; Disorders of cornification


Introduction

  • Disorders of keratinization or cornification alter the surface appearance of the skin by affecting the structure and function of the epidermis. Proliferation, differentiation and desquamation of the stratum corneum or epidermal lipid formation are abnormal. Hyperkeratosis with parakeratotic or orthokeratotic changes is usual and shows as skin that is visibly thickened as well as being thickened on histopathology. Occasionally hypokeratosis is present - usually visible only on histopathology.
  • Keratinization defects also affect transepidermal water loss rates.
  • Cause: congenital or acquired.
  • Signs: may be localized or generalized.
