The new way to diagnose rosacea.


Diagnostic Features

Persistent centrofacial erythema associated with periodic intensification by potential trigger factors.

The major features of this is redness of the skin, which can flare-up when exposed to trigger factors.

Phymatous Changes

The major features of these are papules and pustules, dilate blood vessels, and problems affecting the eyes.

Major Features

  • Flushing/Transient centrofacial erythema.
  • Inflammatory lesions
  • Telangiectasia
  • Ocular Manifestations

Minor Features

  • Burning sensation
  • Stinging sensation
  • Oedema
  • Dry skin

The NRS has provided some more commentary on why they consider this a significant update for rosacea diagnosis and treatment

What the New Classification System Update Means for Rosacea Patients

… the updated classification system, which introduces a new approach to diagnosing rosacea based on individual signs and symptoms. While the original classification system described the most common groupings of signs and symptoms as subtypes, the consensus committee noted that diagnosis should now focus on the individual characteristics that may result from what is now understood as the same disease process. By doing so, they emphasized, the full range of potential signs and symptoms may be taken into consideration.

According to the new system, a diagnosis of rosacea may be considered in the presence of at least one diagnostic sign — either persistent redness of the central facial skin or, less commonly, thickened skin in the central face (known as phymatous changes, often on the nose).

Two or more major signs, including bumps and pimples, flushing, visible blood vessels and eye irritation, may also indicate rosacea. Secondary signs and symptoms, such as burning or stinging, swelling and dry appearance, may also develop but are not diagnostic.

Physicians must rule out other possible causes of rosacea-like symptoms — such as lupus, steroid-induced rosacea or seborrheic dermatitis — before confirming the diagnosis.

As Rosacea News comment in How to diagnose Rosacea has radically changed;

So what has changed?

The difference between the 2 schedules is that now flushing, papules/pustules and telangiectasia on their own are not enough to be diagnosed with rosacea. A red face or or sebaceous / phymatous swelling is now key.
