Spontaneous Clearance of Mycobacterium ulcerans in a Case of Buruli Ulcer

Buruli ulcer (BU) is an infection of skin and soft tissue caused by Mycobacterium ulcerans, a toxin-producing environmental mycobacterium. Significant advances in the treatment of BU have been made over the past decade with the introduction of effective antibiotic therapy and there is a greater understanding of the pathogenesis and host immune response. Although it is generally held that early BU lesions may heal spontaneously, to our knowledge, there are no previously published cases that definitively document spontaneous resolution of culture-confirmed BU.
