[A report of two cases of disseminated cutaneous leishmaniasis in Santander, Colombia].

Leishmaniasis is a zoonosis produced by the transmission of the protozoan leishmania caused by the bite of sand-flies from the Lutzomya specie. Several clinical manifestations present themselves, depending on the infecting strain and the host's immune response; the most frequent variety is localised cutaneous leishmaniasis. Atypical forms sometimes develop, such as the diffuse variety, in which the number of ulcers is greater than 10, thereby affecting several body areas requiring special considerations in its diagnosis and management.
