What to Do When Initial Observation Fails in Leishmania naiffi Cutaneous Leishmaniasis
L. naiffi CL — few, non-cosmetically disfiguring lesions — after observation did not achieve healing
Clinical Scenario
This protocol addresses patients with cutaneous leishmaniasis caused by Leishmania naiffi who present with only a few non-cosmetically disfiguring lesions and in whom initial expectant management has not resulted in complete lesion healing.
Previous Approach and Its Failure Condition
For L. naiffi CL with limited, non-disfiguring lesions, a watch-and-see policy (no antileishmanial treatment) is the appropriate first step. This protocol is indicated when that approach has not achieved its goal: complete reepithelialization of the cutaneous lesion.
Next-Line Treatment Approach
When active intervention becomes necessary, a specific antiparasitic agent is employed to drive complete healing of the lesion.
The complete regimen, dosing, and decision criteria are available in the structured protocol below.
Treatment Goal
The clinical objective is complete reepithelialization — full, confirmed healing — of the cutaneous lesion.

- Therefore, L. naiffi CL calls for a "wait and see" policy when only a few non-cosmetically disfiguring lesions are present.
- In Surinam, patients with five small lesions in total were successfully treated with pentamidine and three small lesions in two patients disappeared without treatment.
