A 39-year-old woman contracted visceral leishmaniasis on a 14-day visit to southern Italy and died of staphylococcal septicaemia before specific treatment could be effective, diagnostic efforts over four months having failed to make the diagnosis until four weeks before death. Eight further cases reported in German-speaking medical journals illustrate similar diagnostic difficulties. The disease is accompanied by septic temperatures, frequently with two daily spikes, hepato- and splenomegaly, normochromic anaemia and leucocytopenia. But diagnosis can only be made by specific tests. The organisms can be discovered in sternal puncture and organ biopsies only if the Giemsa stain is used. Complement-fixation reaction for leishmania should be tried repeatedly, in case the disease is suspected.
