Diagnostic Approach of Maculopapular Rash: In the presence of maculopapular rash, the first question to answer is if the patient has a fever. - If yes, determine if they appear ill or not. If they do, the patient may either have erythema multiforme, rubeola, dengue, Kawasaki disease, rocky mountain spotted fever or Ehrlichiosis. - If they do not appear ill, what they have may be Coxsackievirus, erythema infectiosum, scarlet fever, varicella, gonorrhoeae, drug-induced rash, Epstein-Barr virus, Mycoplasma infection, Roseola infantum, secondary syphilis, or viral infection. If the patient is afebrile, determine if the rash is generalized or localized. - If localized, the maculopapular rash may be due to contact dermatitis, insect bite, scabies, or papular acrodermatitis. - If generalized, determine the chronicity. If chronic, the patient may have molluscum contagiosum, pityriasis, lichen nitidus, pityriasis lichenoides, or papular urticaria. - If acute, the patient may have contact dermatitis, erythema infectiosum, erythema multiforme, pityriasis rosea, roseola, scabies, drug rash, guttate psoriasis, insect bite, Mycoplasma infection, rubella, scabies, secondary syphilis, or other viral infections.
