Each of the coin-like areas might appear dry and scalelike or wet. Some only display a single patch but typically there are many. The oval spots are ruby red, flaming burgundy, and often turn brownish with age. The oval spots bear a striking resemblance to ringworm. If they suddenly manifest, it is imperative you have a trained and skilled professional exam the discoloration to rule out the fungal infection. The plaques can develop on the hands, arms, and trunk but they mostly appear on the legs.

  • Bathe at least once a day. If you cannot bath then take a shower. Use cool or lukewarm water. Avoid the hot setting which can further dry out your skin.
  • Lather on the moisturizer at least twice a day. Ideally, do it right after your bath or shower to lock in the moisture from the water.
  • Keep your body clean. Good hygiene matters.
  • Keep your fingernails and hands clean so you do not spread the infection to the lesions if you should absentmindedly scratch.
  • Avoid scratching or rubbing the spots because excessive irritation will cause irreparable scarring to the skins’ surface.
  • Use topical steroids to help decrease inflammation.
  • Avoid hot, arid regions. Instead, pick a location that is moist and cool. Desert locations tend to make the condition far worse and more frequent.
