Persistent edema of rosacea (chronic upper facial erythematous edema, Morbihan’s disease, rosaceous lymphedema)

Understanding Persistent Edema of Rosacea: An In-Depth Look at Morbihan’s Disease

Persistent edema of rosacea, also known as Morbihan’s disease or rosaceous lymphedema, is a unique and relatively uncommon condition that affects the facial area. It is characterized by a hard, nonpitting edema predominantly seen on the forehead, glabella, upper eyelids, nose, and/or cheeks. This condition often perplexes both patients and healthcare providers due to its elusive nature and resemblance to other facial conditions.

What is Persistent Edema of Rosacea?

Persistent edema of rosacea is a chronic cutaneous condition that manifests as a hard, nonpitting swelling. The term “nonpitting” refers to the fact that pressing on the swollen area does not leave an indentation. This edema typically affects specific areas of the face: the forehead, glabella (the space between the eyebrows), upper eyelids, nose, and cheeks. Although this condition is linked to rosacea, it remains unclear whether it is a distinct disease or a rare complication of rosacea.

The edema usually develops slowly, over months to years, often on a background of ongoing inflammation. This gradual progression means that individuals may experience significant changes in facial contour and persistent redness without much discomfort or other symptoms.

Symptoms and Diagnosis

Symptoms: The primary symptom of persistent edema of rosacea is the noticeable swelling in the facial areas mentioned above. Despite the prominent swelling, there are typically few other symptoms aside from redness and changes in facial contour. The edema worsens gradually and is usually accompanied by chronic inflammation.

Diagnosis: Diagnosing persistent edema of rosacea can be challenging. There are no specific laboratory tests for this condition, and the histological findings are often similar to those seen in rosacea. The differential diagnosis is broad and includes conditions like acne vulgaris, streptococcal cellulitis, Melkersson–Rosenthal syndrome, lupus erythematosus, and sarcoidosis, among others. Accurate diagnosis often involves ruling out these other conditions through clinical evaluation and, in some cases, biopsy.

Treatment Options

Treating persistent edema of rosacea can be difficult, as this condition is generally resistant to standard rosacea treatments. Here’s a breakdown of available treatments:

1. Topical and Oral Antibiotics: While antibiotics are commonly used for treating rosacea, they often prove ineffective for persistent edema of rosacea.
2. Oral Isotretinoin: For severe cases, oral isotretinoin (a potent retinoid) can be beneficial. Typical doses range from 0.5 to 1 mg/kg/day. However, long-term responses to isotretinoin are usually not sustained, necessitating ongoing maintenance therapy.
3. Oral Tetracyclines: Long-term maintenance with oral tetracyclines is often required even after initial treatment with isotretinoin.
4. Eyelid Reduction Surgery: While not a cure, eyelid reduction surgery may improve the cosmetic appearance of the condition. However, it does not alter the disease’s progression.

Conclusion

Persistent edema of rosacea, or Morbihan’s disease, presents a significant diagnostic and therapeutic challenge. Its slow progression and resistance to conventional rosacea treatments make it a condition that requires careful management and ongoing treatment. Although treatment options like oral isotretinoin and tetracyclines can offer some relief, a comprehensive approach to managing symptoms and improving cosmetic outcomes is often necessary.
