In 2016, the global rosacea consensus panel recommended a new classification: at least one diagnostic or two major phenotypes are required for the diagnosis of rosacea. [3]

Diagnostic phenotypes

A diagnosis of rosacea may be considered in the presence of one of the following diagnostic cutaneous signs:

  • Fixed centrofacial erythema in a characteristic pattern that may periodically intensify
  • Phymatous changes: Patulous follicles, skin thickening or fibrosis, glandular hyperplasia, and bulbous appearance of the nose (rhinophyma is the most common form)

Major phenotypes

Without a diagnostic phenotype, the presence of two or more of the following major features may be considered diagnostic:

  • Papules and pustules
  • Flushing: Frequent and typically prolonged
  • Telangiectasia: Predominantly centrofacial in phenotypes I-IV, rarely seen in darker phenotypes
  • Ocular manifestations
