Cutaneous leishmaniasis: an increasing threat for travellers.

Analysis of the literature on cutaneous leishmaniasis in low-prevalence countries suggests an increase in imported cases that is attributable to the growing phenomenon of international tourism, migration and military operations in highly endemic regions. Cases of imported cutaneous leishmaniasis are often missed initially, but diagnosis can be made non-invasively by PCR using skin scrapings of lesions as starting material. Cutaneous leishmaniasis is an emerging threat for travellers and should be considered in all patients presenting with slow-to-heal ulcers.
