When the lesion heals in a year's time it leaves a distinctive depressed hyper pigmented scar. The typical sites are cheeks and arms (exposed areas). Localised Cutaneous Leishmaniasis (LCL) is seen in India in the forests of Rajastan, caused mostly by Leishmania tropica. Himachal Pradesh is repoed as a recent focus.
