Especially adults in tropical, warm and humid areas. The Ulcus tropicum is endemic in the Apsokok nomads in Papua New Guinea (Prescott TAK et al. (2017). Rarely occurring in children.

LocalizationThis section has been translated automatically.

Located mainly on the distal third of the lower legs.

Clinical featuresThis section has been translated automatically.

Formation of single or multiple, rapidly bursting blisters with necrotic bladder base. Ecthyma-like aspect. Spread of necrosis to subcutis, fascia, muscles and periosteum. Scarred healing with hyperpigmented rim, possibly severe contractures that make amputations necessary.

General therapyThis section has been translated automatically.

Treatment of the underlying disease. Sufficient and balancing nutrition. Laboratory control of the total protein, if necessary also of iron, zinc and vitamins.

External therapyThis section has been translated automatically.

Externally disinfecting baths or envelopes (e.g. Betaisodona Lsg. or Quinolinol Lsg. R042. Additional bandages with polyvidon iodine ointments(e.g. Betaisodona ointment).

Notice! If the ulcer does not heal under penicillin or metronidazole, cutaneous leishmaniasis or tuberculosis must be considered!

Internal therapyThis section has been translated automatically.

Depending on the severity, systemic antibiosis, e.g. with benzylpenicillin (e.g. penicillin Grünenthal) once/day 5 million IU i.v. or penicillin V (e.g. megacillin) 3 times/day 1 million IU p.o.

Alterrnatively: broad-spectrum antibiotics such as tetracyclines, erythromycin, cephalosproins, ciprofloxacin.
