A rare case of intranasal vascular leiomyoma.

Vascular leiomyoma (VL) is a solitary and rare form of leiomyoma that usually occurs in the skin or subcutaneous tissue of the lower extremities. Intranasal VL is extremely rare, probably due to the lack of smooth muscle in the nasal cavity. In this study, we report a case of a 70-year-old woman with VL of the inferior nasal turbinate. An endoscopic examination revealed a pinkish globular mass at the inferior turbinate. A preoperative CT scan exhibited a highly enhanced mass originating from the inferior turbinate, and haemangioma was suspected. The patient underwent complete excision of the mass endoscopically, and the histopathological report indicated that the mass was a VL. The tumour was determined to be negative for progesterone and estrogen receptors by immunohistochemical staining. The postoperative period was uneventful. There was no local recurrence during the 12-month follow-up period. 2015 BMJ Publishing Group Ltd.
