General

Rosacea is characterized by the presence of papules and blisters in the cheeks and the nose of an adult. Comedones are absent. The open-colored patients are prone to this disease. Colored patients are rarely offended. The exact cause of rosacea is unknown.

The rapid action of tetracycline indicates the existence of a bacterium responsible for this situation, but there is no absolute and clear identification of any of them. In erasings taken from the lesions Demodex has been found in an increased number after repeated checks, but the importance of the findings has not been clarified.

Clinical Picture

Clinically distinguished inflammatory papules and pustules are found in the central area of the face, especially on the nose.

Lupus papules usually exceed the number of pustules. The erythema can extend up to 1-2 cm beyond the center. Comedones are absent. In severe form, erythema becomes confluent.

Over time it is possible to display teleangiectasis, as well as ocular infestation (e.g. blepharitis, conjunctivitis, dry eye). In a minority of patients hypertrophy of the nose (nasal) occurs, which is not normal and patients should be informed. The teleangiectasis of the face, its translucent appearance, and the intermittent erythema often coexist. Hot drinks, as well as a warm environment can cause sudden vasodilation of the face. When this sudden erythema is the main finding, the diagnosis becomes difficult. The heterodyateral occurrence of rosacea may indicate demodex infection. Edema is possible to develop in rosacea.
