Acne Vulgaris Differential Diagnosis

Differential Diagnosis

The formation of comedones is inherent to the diagnosis of acne vulgaris and when not evident, the following diagnoses may be considered: Keratosis pilaris, perioral dermatitis, rosacea, folliculitis (eosinophilic, pseudomonal, staphylococcal or Malassezia [Pityrosporum] folliculitis), miliaria, and hidradenitis suppurativa. Lastly, dysbiosis from the overuse of antibiotics affects the skin microbiome which also leads to an acneiform condition.
