Diagnosing rosacea is a tricky task for most dermatologists as rosacea symptoms more often than not occur as a combination of problems (acne, eczema, lupus, sarcoidosis, and contact dermatitis) that may or may not be specific to the condition. Any inflammation, redness, or eruptions of the skin could lead an individual to consider rosacea as a diagnosis.
Some major signs of the condition include:
• Temporary redness or flushing of the skin, also known as transient erythema
• Persistent redness of the skin, or non-transient erythema
• Red pimples on the skin
• Visible blood vessels
Secondary signs of rosacea include:
• Skin plaques, characterized by broad, raised portions of the skin.
• Dry skin
• Stinging and burning
• Skin thickening
• Reddish and bulbous growths on the nose known as rhinophyma.
To test for rosacea, a dermatologist first conducts a physical examination of the eyes and the skin. Based on a patient’s symptoms, other tests can be employed individually or together. Some tests commonly performed in diagnosing rosacea are:
• Standardized skin surface biopsy
• Potassium hydroxide examination
• Individual bacterial cultures
• Antibiograms
• Mucin clot test
• Patch tests
• Photopatch tests
• Appropriate blood tests
• Radiological examinations
