Case Report: Miltefosine Failure and Spontaneous Resolution of Cutaneous Leishmaniasis braziliensis.

Cutaneous leishmaniasis (CL) is often caused by Leishmania braziliensis (L. braziliensis) in South America. Because of the risk for mucocutaneous leishmaniasis, L. braziliensis is frequently treated with parenteral or oral medications. Here, we present a case of a young woman with L. braziliensis (CL) that did not respond to miltefosine but eventually experienced spontaneous resolution. This case highlights the potential for treatment failure and the importance of clinical monitoring in the setting of cutaneous leishmaniasis caused by L. braziliensis.
