Buruli ulcer

Buruli ulcer is an indolent necrotizing disease of the skin, subcutaneous tissue, and bone that is caused by Mycobacterium ulcerans. Buruli ulcer is presently the third most common mycobacterial disease of humans, after tuberculosis and leprosy, and the least understood of the three. The disease remained largely ignored by many national public health programs, but more recently, it has been recognized as an emerging health problem, primarily due to its frequent disabling and stigmatizing complications. The contribution discusses various aspects of Buruli ulcer, including its geographic distribution, incidence, and prevalence; mode of transmission, pathogenesis, and immunity; clinical manifestations; laboratory diagnosis; differential clinical diagnosis; and treatment.
