A rash of the skin consisting of numerous scattered patches could be many different diagnoses.

  • A form of psoriasis called guttate psoriasis presents as red, scaly patches of the body often after strep throat. Guttate psoriasis is commonly located on the arms, legs and torso.
  • Pityriasis Rosea is a rash of red, scaly patches predominantly on the trunk and is typically caused by a virus.
  • Secondary syphilis can also present with red, scaly patches of the body and needs an antibiotic to be treated.

If a rash of scattered patches on the body is persisting on the skin, it is best to see a dermatologist for evaluation and treatment.
