However patients often present with a varied range of symptoms that overlap these sub-types.7 As an example, patients may present with papulopustular rosacea and also persistent erythema, and even if the PPR is treated successfully the erythema either transient or fixed may Figure 2 still remain. Erythematotelangiectatic rosacea (ETTR) Rosacea features can span multiple subtypes and progress between subtypes. Therefore, their clinical presentation may be more accurately defined by the term phenotype (individual features), which describes an individual’s observable characteristics that can be influence by genetic or environmental factors. Subtype classification may not fully cover the range of clinical presentations and is likely to confuse severity assessment, whereas a phenotype-based approach could improve patient outcomes by addressing an individual patient’s clinical presentation and their concerns. Tan et al suggests that adopting a phenotype led approach will Figure 3 address rosacea and its treatments in Papulopustular (PPR)I a way that is more consistent with the individual’s experience.8 The disease is unpredictable and can vary from week to week for patients. This can affect the patient’s quality of life. In addition to the physical impact, it is well documented that patients report significant psychological distress owing to the sometimes dramatic changeable nature of the signs and symptoms. The National Rosacea Society (NRS) conducted a survey of 1,675 patients, of which 90% of respondents said the effects of the disease on their personal appearance had lowered their self-esteem and self-confidence; 88% reported embarrassment; and OM C others noted feelings of frustration .
