[Multilocular mucocutaneous leishmaniasis with perforation of the anterior nasal septum: a rare differential diagnosis].

Leishmaniasis, caused by protozoa of the genus Leishmania, comprises visceral, cutaneous, and mucocutaneous forms. It is mainly endemic in South and Central America as well as the Mediterranean region, while being very rare in Europe. Mucocutaneous leishmaniasis may affect the nasal and oral mucosa, and the current case highlights the importance of interdisciplinary collaboration: both cutaneous and mucocutaneous lesions with nasal septum perforation were present. Close cooperation between the departments of otorhinolaryngology, infectious diseases, and tropical medicine are key to ensuring rapid and sufficient treatment.
