Buruli's ulcer: three cases diagnosed and treated in France.

The authors report three cases of skin ulcer, called Buruli's ulcer. This is a tropical disease, caused by Mycobacterium ulcerans. The diagnosis is often belated, because the infection is rare in Europe. Diagnosis is based on the clinical aspects, and can be confirmed by a biopsy and a molecular study. A culture is needed to test antibiotics. Treatment is always surgical, including a wide excision of all lesions, and specific oral antibiotics for 6 months.
