They are transmitted to humans through the bite of an infected sandfly. The cutaneous (skin) form is the most common. The lesions generally heal, though scarring is possible. Treatment is by drugs or by cryotherapy. Leishmania parasites are found in subtropical and tropical regions worldwide. In this case the infection occurred in a northern region of Iran.
