Erythrotelangiectatic rosacea

Erythrotelangiectatic rosacea, also known as erythematotelangiectatic rosacea a subtype of rosacea characterized by persistent redness and flushing, as well as the development of visible blood vessels (telangiectasias) on the skin with the presence of erythema (redness), telangiectasias (dilation of small blood vessels), and flushing. This subtype is also known as “red face rosacea” due to the prominent redness and flushing symptoms.

Causes

The exact causes of this condition are not fully understood, but a combination of factors likely contribute to its development. These include:

  1. Genetic predisposition: Some individuals may have a genetic predisposition to developing rosacea, which increases their risk of developing erythrotelangiectatic rosacea.
  2. Environmental factors: Exposure to certain environmental factors, such as sun exposure, wind, cold, and heat, can trigger rosacea symptoms and exacerbate erythrotelangiectatic rosacea.
  3. Hormonal changes: Hormonal changes, particularly those that occur during menopause, can lead to an increase in the risk of developing erythrotelangiectatic rosacea.
  4. Vascular abnormalities: Some individuals with erythrotelangiectatic rosacea may have abnormal blood vessels in the skin, which can contribute to the development of the condition.
  5. Microorganisms: Studies have suggested that certain microorganisms, such as Demodex mites and H. pylori bacteria, may play a role in the development of erythrotelangiectatic rosacea.
  6. Medications and cosmetics: Certain medications, such as vasodilators, and cosmetics, can trigger rosacea symptoms and exacerbate erythrotelangiectatic rosacea.

It is important to note that the specific causes of erythrotelangiectatic rosacea may vary from person to person and that not everyone will experience the same triggers.

Symptoms

Symptoms of erythrotelangiectatic rosacea may include:

  • Persistent redness and flushing of the face, especially the cheeks, nose, and forehead
  • Visible blood vessels (telangiectasias) on the skin, particularly on the cheeks and nose
  • Burning or stinging sensations on the skin
  • Swelling or puffiness of the face, particularly around the eyes
  • Sensitivity to certain skin care products or cosmetics

Erythrotelangiectatic rosacea can be difficult to treat and manage. Treatment options may include topical medications such as metronidazole or azelaic acid, oral medications such as tetracyclines or isotretinoin, and laser or light therapy to reduce the appearance of blood vessels.

Diagnosis

The test involves applying a small amount of the substance in question to a small area of skin, typically on the inner forearm, and observing the reaction over a period of time.

The erythema test is typically used to diagnose allergic contact dermatitis, a type of skin inflammation that occurs as a reaction to an allergen. It can also be used to test for sensitivity to certain chemicals or other irritants, such as fragrances or preservatives in cosmetics or skincare products.

During the test, the skin will be examined for signs of redness, itching, or other irritation. The severity of the reaction will be graded on a scale, with mild reactions being classified as grade 1 and severe reactions being classified as grade 4.

The erythrotelangiectatic test is a simple and non-invasive procedure that can be performed in a dermatologist’s office or other medical setting. It is considered a reliable and accurate way to diagnose allergic contact dermatitis and other skin reactions.

Treatment

Treatment options for this condition include:

  1. Topical medications: Metronidazole, azelaic acid, and ivermectin are commonly used topical medications that can help reduce redness and inflammation.
  2. Oral antibiotics: Tetracyclines such as doxycycline and minocycline are often prescribed to help control inflammation and reduce the number of acne-like lesions.
  3. Laser therapy: Vascular lasers such as the pulsed dye laser can help reduce the appearance of blood vessels on the face.
  4. Photodynamic therapy: This treatment involves applying a topical solution to the skin and then exposing the area to a specific wavelength of light. This can help reduce redness and inflammation.
  5. Lifestyle changes: Avoiding triggers such as alcohol, spicy foods, and hot beverages can help reduce the frequency and severity of flare-ups.
