A: Cutaneous Leishmaniasis
Answer: A: Cutaneous Leishmaniasis 
Explanation: A typical lesion of Acute Cutaneous Leishmaniasis is papule at the site of the sand fly bite which enlarges and breaks down in the centre. The ulcer usually has a rolled border. 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.
