Clinical Classification

Clinical Information

  • Porokeratosis

    a heritable disorder of faulty keratinization characterized by the proliferation of abnormal clones of keratinocytes and lesions showing varying atrophic patches surrounded by an elevated, keratotic border. these keratotic lesions can progress to overt cutaneous neoplasm. several clinical variants are recognized, including porokeratosis of mibelli, linear porokeratosis, disseminated superficial actinic porokeratosis, palmoplantar porokeratosis, and punctate porokeratosis.
  • Keratinocytes

    epidermal cells which synthesize keratin and undergo characteristic changes as they move upward from the basal layers of the epidermis to the cornified (horny) layer of the skin. successive stages of differentiation of the keratinocytes forming the epidermal layers are basal cell, spinous or prickle cell, and the granular cell.
  • Porokeratosis

    a clonal proliferation of abnormal keratinocytes characterized by the development of localized or multiple atrophic skin patches surrounded by an annular keratotic ring called cornoid lamella.

Patient Education


Sun Exposure

Ultraviolet (UV) rays are an invisible form of radiation. They can pass through your skin and damage your skin cells. Sunburns are a sign of skin damage. Suntans aren't healthy, either. They appear after the sun's rays have already killed some cells and damaged others. UV rays can cause skin damage during any season or at any temperature. They can also cause eye problems, wrinkles, skin spots, and skin cancer.

To protect yourself :

  • Stay out of the sun when it is strongest (between 10 a.m. and 2 p.m.)
  • Use sunscreen with an SPF of 15 or higher
  • Wear protective clothing
  • Wear wraparound sunglasses that provide 100% UV ray protection
  • Avoid sunlamps and tanning beds

Check your skin regularly for changes in the size, shape, color, or feel of birthmarks, moles, and spots. Such changes are a sign of skin cancer.
