A 79-year-old male suffering from nasal congestion was referred to our hospital. Endoscopic examination revealed a hyperemic mass obstructing the left nasal passage. The lesion's surface was smooth. The findings of imaging studies were consistent with a benign tumor despite the erosion and perforation of the septum. The lesion originated from the middle concha and was attached to it with a thin stalk. It was removed easily by endoscopic resection. Histopathology revealed significant infiltration of mononuclear inflammatory cells, mostly lymphocytes and histiocytes, into the edematous subepithelial connective tissue. High-power magnification showed numerous Leishmania amastigotes in the cytoplasm of the histiocytes. A polymerase chain reaction experiment for Leishmania also confirmed the morphological diagnosis. No relapse was observed in the 12 months after surgery and the patient was doing well.
