Background: Morbus Morbihan is a rare complication of rosacea, consisting of a persistent lymphoedema of the upper part of the face. It has typically a chronic course, unspecific histopathological findings and an extreme refractoriness to therapy.
Patients and methods: Between February 2008 and January 2010, 5 patients with Morbus Morbihan were observed at the Department of Ophthalmology of the University Medical Centre Mainz. In the present cohort study, we describe the clinical, laboratory and histological findings that led to the diagnosis. The course of the affection and the results of different therapeutic options are also reported.
Results: Each patient underwent a complete ophthalmological examination, as well as general and dermatological consultations. All patients showed facial skin alterations typical for rosacea. 4 out of 5 subjects underwent a lid biopsy to confirm the diagnosis of Morbus Morbihan, one patient refused it. Initial treatment consisted of various systemic and local medical therapies, however, with poor success. One patient had intravenous therapy with corticosteroids elsewhere with no effect. We treated 3 cases with intralesional triamcinolone injections with good results. 2 patients underwent upper lid blepharoplasty. Results of surgery remained stable also due to manual lymph drainage and intralesional injections of triamcinolon. No complications or side effects were seen in patients treated with triamcinolone.
Conclusions: Morbus Morbihan can be diagnosed only after excluding other conditions leading to chronic lid swelling. In our series, good results were achieved with intralesional injection of triamcinolone. Surgery also led to relevant improvements for a long period (13 months), with some adjuvant therapy. The treatment of chronic eyelid oedema associated with rosacea remains a challenge for the ophthalmologist and the oculoplastic surgeon.
