[A multifocal form of cutaneous leishmaniasis caused by Leishmania infantum in an immunocompetent child treated with a short course of liposomal amphotericin B]

Background: Cutaneous leishmaniasis (CL) is a parasitic infestation caused by various species of Leishmania protozoa transmitted by the bite of phlebotomine sand flies. Herein we report a case of multifocal CL due to Leishmania infantum in an immunocompetent child treated with liposomal amphotericin B.

Patients and methods: A 10-month-old baby was referred for multiple ulcerated nodules of the face and upper limbs present for 5 months and following travel to North Morocco. Histological and parasitological examinations resulted in a diagnosis of CL due to L. infantum. The child was treated with intravenous liposomal amphotericin B in accordance with the schedule for visceral leishmaniasis (10mg/kg over 2 days), and rapid improvement of the lesions was seen within 10 days.

Discussion: Clinical polymorphism of CL exists according to the infecting species. The multifocal presentation in our patient is very unusual for CL due to L. infantum in an immunocompetent child. To our knowledge, there have been no previous reports of successful use of parenteral liposomal amphotericin B for CL caused by L. infantum as described in our case.
