Vascular Leiomyoma of the Nasal Floor: The Risk of Misdiagnosis

ABSTRACT

Vascular leiomyoma (VL) is a rare tumor, particularly in the sinonasal region. The etiology of VL is unclear and there are a number of theories regarding how VL develops. To date, approximately 20 cases of VL have been reported in the sinonasal area. This is the first reported case of VL in the right nasal floor. We present the case of an adult patient with mild nasal obstruction and discomfort. Preoperative examination failed to accurately diagnose the patient with VL. Transnasal endoscopic resection was performed. There were no complications or recurrence postoperatively.
