Answer: Seborrhea and rosacea

Any combination of the topical treatment options can be effective.

Lupus would be tender and more indurated. Sarcoidosis can mimic most diseases; biopsy would be required if the patient did not respond to the topical therapies. Contact dermatitis would be more pruritic than the rash seen here, and the patient would typically have an exposure history.
