title: [Cutaneous leishmaniasis caused by Leishmania mexicana in Durango, Mexico: first clinical case report].
abstract: BACKGROUND
  Leishmanisis is a parasitic diseases caused by intracellular protozoan of Leishmania genus. These parasites are transmitted by the bite of phlebotomine flies. Leishmanises are classified in different clinic variants: cutaneous localized or diffuse, mucocutaneous and visceral. In Mexico, the leishmanisis are distributed in several states, however Durango was considered free of leishmaniasis.
  
  
  METHODS
  A 9 year old male patient with an ulcerated pruriginous node of circular shape, 13 x 18 mm diameter, localized in the back of the right arm with 6 months progression. The patient was a permanent resident of Durango, Mexico. Histopathology evidenced macrophages infected with amastigotes. The PCR-RFLP result was consistent with Leishmania mexicana. Treatment with glucantime was satisfactory.
  
  
  CONCLUSIONS
  Here we report the first clinical case of leishmanisis cutaneous localized caused by Leishmania mexicana from Durango, Mexico in a 9 years old male, confirming the increasing propagation of this protozoan parasite in Mexico.
