International audience. OBJECTIVES: Cutaneous leishmaniasis (CL) in Asia, Northern, and Sub-Saharan Africa is mainly caused by Leishmania major and Leishmania tropica. We describe and evaluate the treatment outcome of CL among travelers and migrants in Europe.METHODS: We conducted a retrospective study of parasitological confirmed CL cases caused by L. major and L. tropica during 2013-2019 in Europe. Data were collected from medical records and databases within the LeishMan network.RESULTS: Of 206 included cases of CL, 75 were identified as L. major and 131 as L. tropica. Of patients with L. tropica infection, 80% were migrants, whereas 53% of patients with L. major infection had been visiting friends and relatives. Among patients with L. tropica, 48% were younger than 15 years. Pentavalent antimony cured 73% (L. major) and 78% (L. tropica) of patients. The cure rate for intralesional administration was 86% and 67% for systemic, on L. tropica. Liposomal amphotericin B had a cure rate of 44-63%. CONCLUSION: L. major infections were mostly found in individuals visiting friends and relatives, whereas L. tropica were mainly identified in migrants. No patients with L. major relapsed. Pentavalent antimony, liposomal amphotericin B, and cryotherapy had cure rates in accordance with previous studies.
