Buruli ulcer.

  • Atypical mycobacteriosis caused by Mycobacterium ulcerans.
  • Infection with the atypical mycobacterium, Mycobacterium ulcerans, an obligatory pathogen
  • 3. most frequent mycobacteriosis in immunocompetent persons
  • Mainly found in the tropics and subtropical regions
  • Pathogen: Mycobacterium ulcerans.
  • Incubation time: 2-14 weeks.
  • The path of infection is not clear. Possibly via contaminated soil, plants, possibly insects or from person to person.
  • Painless, slightly scaly, centrally draining, partly oedematous nodules on the legs or trunk, which in the course of time develop into a size-progressive ulcer (up to 15% of KOF)
  • In rare cases there is involvement of the fascia, muscles and bones
  • Clinical features.
  • Bact. smear

Granulomas with giant Langerhans cells, acanthosis, hyperkeratosis.

The occurrence of widespread necroses and the sowing of mycobacteria on the bones is possible. Spontaneous remission with scarring is possible.

  • If the disease is detected early, a widespread excision is indicated.
  • Systemic therapy has so far shown little promise of success.
