The clinical manifestations of different types of rosacea vary and are characterized by symptoms such as skin flushing, erythema, papules, pustules, and purplish nodules. Rosacea is a chronic inflammatory skin disease that occurs on the face. Rosacea can be categorized into erythematous capillary dilatation, papular-pustular, and hypertrophic, and the symptoms may vary from one type to another. 1. Erythematous capillary dilatation: The main symptom is flushing (caused by capillary dilatation) or erythema on the face, which is aggravated by food stimulation or sudden changes in external temperature. 2. Papule-pustule type: with the continuous development of the disease, the patient’s face can gradually appear pinhead or mung bean size papules and pustules. Skin damage can last for several years or more. 3. Hypertrophy: Hypertrophy is mostly seen in the patient’s nose, on the basis of erythema or capillary dilatation, the tip of the nose is enlarged and forms purplish-red nodular elevations of varying sizes. If not effectively treated or controlled for a long time, fibrotic nodules can be formed in the late stage. When patients find the above symptoms, they should go to the dermatology department in time for relevant examination, and find out the problem as early as possible to avoid delaying the condition.
