Mucosal Leishmaniasis: An Underestimated Presentation of a Neglected Disease

الملخص EN

We present a review of current knowledge about mucosal leishmaniasis (ML).

Although involvement of mucous membranes is classically admitted in New World leishmaniasis, particularly occurring in infection by Leishmania (L.) braziliensis species complex, ML is also a possible presentation of Old World leishmaniasis, in either L.

donovani or L.

major species complex infections.

Thus, ML has to be considered not only as a Latin American disease but as an Old and New World disease.

We describe ML epidemiology, pathogenesis, clinics, diagnosis, and therapy.

Considering both its highly disfiguring lesions and its possible lethal outcome, ML should not be underestimated by physicians.

Moreover, leishmaniasis is expected to increase its burden in many countries as sandfly vector distribution is widespreading towards non-endemic areas.

Finally, the lack of clear understanding of ML pathogenesis and the absence of effective human vaccines strongly claim for more research.
