Secondary signs and symptoms

• Secondary signs and symptoms may appear with 1 or more diagnostic or major phenotypes and may include the following.

  • Burning or stinging. May occur typically on erythematous skin without scales, although scaling may also occur, especially on malar skin.

  • Oedema. Facial oedema may accompany or follow prolonged erythema or flushing.

  • Dry appearance. Central facial skin may be rough and scaly so as to resemble dry skin and suggest an eczematous dermatitis, and rosacea may often include the co-existence of seborrhoeic dermatitis.
