Study Notes
Understanding Psoriasis
- Psoriasis is an autoimmune condition that leads to the rapid turnover of skin cells.
- It typically results in the formation of red, scaly patches known as psoriatic plaques.
Causes of Psoriatic Patches
- The red, scaly patches are caused by an overactive immune response, which triggers inflammation.
- Factors contributing to the flare-ups may include genetics, stress, environmental factors, and lifestyle choices.
Common Locations of Psoriatic Plaques
- Psoriatic plaques commonly occur on the elbows, knees, scalp, lower back, and sometimes the palms and soles of the feet.
Skin Cell Production Rate
- In psoriasis, new skin cells are produced at an accelerated rate, typically every 3-4 days compared to the normal rate of 28-30 days.
Characteristic Appearance of Psoriatic Skin
- The skin at psoriatic sites appears thickened, red, and covered with silvery-white scales due to the rapid accumulation of cells.
