CL (cutaneous leishmaniasis); DCL (disseminated cutaneous leishmaniasis).
Except patient 1 that received 10 mg Sbv/Kg/day on the first treatment, the others received low doses of pentavalent antimony (5 mg Sb/kg/day) with continuous or intermittent schedules or also intralesional injection (patients 4, 5, 6, 7, 10, and 12). All patients were retreated with repetition of the first therapeutic schedules. Five patients (1, 4, 7, 9, and 10) required one-third treatment with drugs of second line.
