Abstract
Leishmaniasis is an infectious disease caused by a protozoon of the genus Leishmania. It can manifest as cutaneous, mucosal, localized lymphadenitis forms or it can result as multiorgan involvement. In this article we present the case of a 59-year-old male with a polypoid mass attached to the septum at the right nasal cavity and symptoms as nasal congestion, hyposmia and anterior rhinorrhea. Histological sections of the mass showed oval-shaped inclusions in the cytoplasm of histiocytes suspicious for Leishmania amastigotes. The diagnosis was confirmed by detection of Leishmania complex DNA with polymerase chain reaction (PCR).
