Cutaneous New World leishmaniasis-sporotrichosis coinfection: report of 3 cases.
Three cases of coinfection with Leishmania and Sporothrix spp in the same lesion are described. The patients had ulcers with erythematous borders and regional lymphadenopathy. The diagnosis of leishmaniasis was accomplished by direct visualization of the amastigotes or culture of the promastigotes, or both. The diagnosis of sporotrichosis was proved in two cases by culture of Sporothrix schenckii and by the histopathologic features in one case. All patients had a positive sporotrichin test. Two patients responded successfully to oral potassium iodide. One patient received oral itraconazole 100 mg/day because of intolerance to iodides and was cured. To our knowledge coinfection with Leishmania and Sporothrix spp has not been reported. The use of empirical treatments for leishmaniasis such as poultices or puncturing of the lesion with thorns or woods splinters might introduce Sporothrix and explain the coinfection.
