  • LICHEN PLANUS-. an inflammatory pruritic disease of the skin and mucous membranes which can be either generalized or localized. it is characterized by distinctive purplish flat topped papules having a predilection for the trunk and flexor surfaces. the lesions may be discrete or coalesce to form plaques. histologically there is a "saw tooth" pattern of epidermal hyperplasia and vacuolar alteration of the basal layer of the epidermis along with an intense upper dermal inflammatory infiltrate composed predominantly of t cells. etiology is unknown.
  • LICHEN PLANUS ORAL-. oral lesions accompanying cutaneous lichen planus or often occurring alone. the buccal mucosa lips gingivae floor of the mouth and palate are usually affected in a descending order of frequency. typically oral lesions consist of radiating white or gray velvety threadlike lines arranged in a reticular pattern at the intersection of which there may be minute white elevated dots or streaks wickham's striae. jablonski illustrated dictionary of dentistry

Information for Patients

Skin Conditions

Your skin is your body's largest organ. It covers and protects your body. Your skin

  • Holds body fluids in, preventing dehydration
  • Keeps harmful microbes out, preventing infections
  • Helps you feel things like heat, cold, and pain
  • Keeps your body temperature even
  • Makes vitamin D when the sun shines on it

Anything that irritates, clogs, or inflames your skin can cause symptoms such as redness, swelling, burning, and itching. Allergies, irritants, your genetic makeup, and certain diseases and immune system problems can cause rashes, hives, and other skin conditions. Many skin problems, such as acne, also affect your appearance.
