Mucocutaneous Leishmaniasis in HIV-Related Immune Reconstitution Syndrome.

Immune reconstitution inflammatory syndrome (IRIS) is an immuno-pathologic reaction to quiescent opportunistic microbial pathogens upon restoration of underlying immune defects. Here we report a Honduran patient with HIV/AIDS who developed a facial rash worsening on antiretroviral therapy and increasing CD4 count. Culture and PCR analysis from the skin biopsy identified Leishmania panamensis, which was effectively treated with long-term liposomal amphotericin B. This is the first report of mucocutaneous leishmaniasis (MCL)-associated IRIS due to L. panamensis.
