[Leish-l] Auricular leishmaniasis

[Martin Sanchez]

Dear Flavio, What you describe is widely known as the Koebner phenomenon
and ussually ocurrs long after to certain cutaneous pathologies or lesions
  including CL lesions. They also tend to be secondary lesions with no
detectable parasites at least by conventional techniques but the
inflammatory process leading to the formation of the injury occurs
completely. These new lesion usually occurs after trauma (irritation burn,
etc) there are several references to this and cutaneous leishmaniasis. Also
some authors might risk to infer that this could be the phenomenon in some
cases, that originate mucosal lesions in immune suppresed patients,  years
after a healed skin CL lesions  or the, or the appearance of a cutaneous
lesion years after having visited an endemic zone.
