The manifestations of rosacea are fluctuating: this skin condition evolves by outbreaks interspersed with periods of remission. Rosacea is one of the symptoms of rosacea .
Different types of rosacea are found:
- Vascular rosacea : this is the most frequently found type. Vascular abnormalities are associated with various external factors and are responsible for the development of abnormal blood circulation: this is characterized by excessive vasodilation of micro vessels, telangiectasias . The main diagnostic element is the facial redness which disappears with vitropression (that is to say which disappears when the affected area is pressed). The blood flow is responsible for the redness, or erythrosis , observed on the skin and a sensation of heat specific to rosacea. This inflammatory and chronic skin condition manifests itself mainly in theface : cheeks, sides of the nose , forehead, chin.
- Ocular rosacea may accompany vascular rosacea. Extremely unpleasant symptoms: blurred vision, conjunctivitis, red eyes , burning, photophobia (hypersensitivity to light), feeling of sand in the eyes.
- Papulo-pustular rosacea : also known as acne rosacea , it can be confused with hormonal acne. The presence of red and painful papules and pustules makes it possible to differentiate papulo-pustular rosacea from the rest of the forms.
- Hypertrophic rosacea affects the nose which has a red, bulging tip , with possible appearance of a protrusion called rhinophyma .
- Rosacea fulminans or facial pyoderma: this form affects women more frequently and appears suddenly, it is a rare but serious form. Hormonal variations seem to be involved.
