Diagnosis of Leishmania infection in a nonendemic area of South America.

American tegumentary leishmaniasis is the generic name for a variety of cutaneous and mucocutaneous presentations of parasitosis caused by several species of the genus Leishmania. This is a widespread infection in the American continent, from the South of the United States to the North of Argentina. We herein describe the management of a patient with American tegumentary leishmaniasis in Mendoza, Argentina, a nonendemic area of South America, whose diagnosis and treatment were significantly delayed, because the patient did not report a recent history of travel to any known endemic areas. This case stresses the need for training health-care professionals in the diagnosis and treatment of not only endemic parasitosis within their work zones but also nonendemic parasitosis.
