Vascular Leiomyoma Arising From the Nasal Floor Misdiagnosed as a Nasolabial Cyst in an 74-Year-Old Patient

Abstract

Leiomyoma is a benign tumor that originates from smooth muscle and can develop anywhere in the body where smooth muscle is present. However, leiomyoma arising in the head and neck region are very rare. We experienced a case of a 74-year-old male patient with a right nasal floor mass. The patient complained of bleeding from the right nasal cavity, nasal congestion, and discharge. On physical examination, a relatively smooth-surfaced, well-demarcated mass was observed in the right nasal floor. Preoperative imaging was interpreted as a right nasolabial cyst, and endoscopic excision was performed. Histologic examination confirmed it to be vascular leiomyoma. The patient was followed up for 6 months postoperatively and remains stable with no recurrence of symptoms. We report a case of vascular leiomyoma arising from the nasal floor that was mistaken for a nasolabial cyst in a 74-year-old patient.
