Cutaneous Leishmaniasis Mimicking Pyoderma Gangrenosum.

ABSTRACT

Cutaneous leishmaniasis (CL) is caused by leishmania, a single-called parasite and is transmitted the bite of sand fly. It characterized by ulcers, which are usually without pain or pruritus. Both old world and new world species cause localized CL. Old world disease begins as a small erythematous papule at the site of the bite of the sand fly and over several weeks it enlarges up to 3 cm eventually becoming eroded and crusted. After lasting for several months the ulcer heals with a slightly depressed scar. We report the case of a 27-year-old man native of South India, carpenter by occupation, working in Saudi Arabia for >5 years who presented with a painful ulcer of 10 cm in diameter over his right shoulder with purulent discharge. He was diagnosed to have CL and was treated with intramuscular injection of sodium stibogluconate 20 mg/kg/day for 30 days. The resultant cribriform scar resembled that of pyoderma gangrenosum.
