ICD-11

Leishmaniasis is due to infection by vector-borne protozoa from the genus Leishmania. These protozoa exist as obligate intracellular parasites in human and mammalian hosts and are transmitted from host to host by certain species of sandfly. Depending on the Leishmania species involved, the resultant disease picture may range from a localised cutaneous ulcer through extensive mucocutaneous destruction to severe systemic disease.

Mucocutaneous leishmaniasis is a secondary infection of nasal and oral mucosae, predominantly by Leishmania braziliensis. It usually first manifests within two years of initial cutaneous infection but often after the latter has healed. It results from lymphatic or haematogenous spread of infection and can cause severe local tissue destruction.
