Angular Cheilitis: Symptoms, Treatment, and Contagion Risks - Dermatology

More Info

---

Angular cheilitis, also known as angular stomatitis or perleche, is a condition characterized by inflammation and cracking at the corners of the mouth. This condition can be caused by a variety of factors, including nutritional deficiencies, particularly of B vitamins (such as riboflavin and vitamin B12), iron deficiency, and certain medical conditions that compromise the immune system. It can also be exacerbated by habits such as licking the lips or wearing ill-fitting dentures, which can create a moist environment conducive to fungal or bacterial infections.


Symptoms of Angular Cheilitis
The primary symptoms of angular cheilitis include:
- Redness and swelling at the corners of the mouth.

- Cracks or fissures that may bleed or become painful.

- Itching or burning sensations in the affected area.

- In severe cases, the cracks may become infected, leading to further discomfort.


Treatment Options
Treatment for angular cheilitis typically focuses on addressing the underlying cause and relieving symptoms. Here are some common approaches:
1. Topical Treatments: Over-the-counter antifungal creams (like clotrimazole or miconazole) can be effective if a fungal infection is suspected. If a bacterial infection is present, topical antibiotics may be prescribed.

2. Nutritional Supplements: If angular cheilitis is linked to nutritional deficiencies, supplements such as vitamin B complex or iron may be recommended. A healthcare provider can perform blood tests to determine if deficiencies are present.

3. Moisturizers: Applying a barrier cream or lip balm can help protect the corners of the mouth from moisture loss and irritation.

4. Good Oral Hygiene: Maintaining proper oral hygiene and ensuring that dentures fit well can help prevent irritation and subsequent infections.

5. Avoiding Irritants: Identifying and avoiding any irritants, such as certain foods or dental products, can also be beneficial.


Contagion Risks
Angular cheilitis is not contagious. It is primarily a result of local factors, such as moisture accumulation, nutritional deficiencies, or underlying health conditions. However, if the cracks become infected, there is a risk of spreading the infection if proper hygiene is not maintained. It is essential to avoid sharing utensils, lip products, or towels with others to minimize any risk of infection.


Distinguishing Angular Cheilitis from Other Conditions
When differentiating angular cheilitis from other conditions, such as herpes simplex virus infections or contact dermatitis, consider the following:
- Herpes Simplex: This condition typically presents with painful blisters or sores rather than just cracks. It is contagious and usually resolves with antiviral medications.


- Contact Dermatitis: This may result from an allergic reaction to certain products and can cause redness and irritation, but it usually affects a broader area rather than being localized to the corners of the mouth.


Conclusion
If you suspect you have angular cheilitis, it is advisable to consult a healthcare professional for an accurate diagnosis and appropriate treatment plan. They can help identify any underlying causes and recommend the best course of action. In the meantime, maintaining good oral hygiene, ensuring adequate nutrition, and protecting the affected area can help alleviate symptoms and promote healing.
