This study investigated clinical, laboratorial, therapeutic and prognostic aspects of American cutaneous leishmaniasis in Belo Horizonte in 358 patients with cutaneous leishmaniasis (CL) and 25 with mucocutaneous leishmaniasis (MCL). Compared to CL patients, the MCL patients reported longer duration of disease and higher frequency of other diseases, suggesting that debilitation caused by leishmaniasis or other conditions might contribute to activation and/or mucous dissemination of the parasite. The sensitivity of skin test, indirect immunofluorescence reactions and direct detection of parasites was 78.4, 79.3 and 68.3%, respectively. The treatment with meglumine antimoniate presented 100% efficacy, but 59% patients had side-effects. During two years of follow-up, there were 32/318 relapses after successful treatment. Most relapses (31/32) were of CL patients treated with 15 mg Sb5+/kg/day. The negative response to skin test was the only factor associated with a significant threefold increased risk of relapse. Higher dose or longer duration of treatment might improve the prognosis in these patients.
