Maculopapular - Diagnostic Algorithm

Pathophysiology:

- Catch-all term with a wide range of potential pathophysiologic mechanisms and causative etiologies.

- Any process that results in erythroderma, petechiae, or fluid-filled lesions may start as a macule or papule.

- Pathophysiology is of little guidance in this category where we must instead rely on the patient’s history and identification of red-flags to exclude dermatologic emergencies.

High-risk Features (Identified by dermatologists to stratify urgency of inpatient consultations):

- Ill-appearing, vital sign instability

- New-onset fever with rash

- Mucocutaneous or ocular lesions

- Recent introduction of anti-convulsant or sulfa-drug

- Skin pain

- Immunocompromised
