Case 3: Steroid Acne

The patient has steroid acne, E, the result of long-term use of a halogenated corticosteroid. Discontinuation of the medication led to resolution of the rash in 8 weeks.

 

Rosacea and acne are usually more symmetric. Gram-negative folliculitis is usually somewhat tender. Pityrosporum folliculitis is smaller, monomorphic, and pruritic.
