The lesions do not ulcerate and spread locally and at distant sites Depending on the clinical history and presentation, CL may be classified as localized CL (LCL), mucocutaneous leishmaniasis (MCL), disseminated leishmaniasis, diffuse leishmaniasis, or lesihmaniasis recidivans.

The localized cutaneous lesions often have an incubation period from 2 to 4 weeks at which time an asymptomatic papule, multiple papules, or nodules occur at the site of inoculation Uncommon types• Diffuse cutaneous leishmaniasis (DCL): Caused by L. aethiopica, diffuse nodular non- ulcerating lesions. Low immunity to Leishmania antigens, numerous parasites.• Leishmaniasis recidiva (lupoid leishmaniasis): Severe immunological reaction to Leishmania antigen leading to persistent dry skin lesions, few parasites Most cases of diffuse cutaneous leishmaniasis, post-kala-azar dermal leishmaniasis, and leishmaniasis recidivans are chronic and resistant to treatment. These forms can be exceedingly disfiguring cosmetically because of the degree of persistent involvement; however, they are associated with low mortality rates A mouse model of diffuse leishmaniasis has been developed to address the question of how a cold ambient temperature can influence the clinical presentation of leishmaniasis. Notably, the experiments were performed in the most severe disease model available (Barral et al. 1983 ; Hill et al. 1983 ; Roberts et al. 1989 ) in order to maximize the.
