We report a case of vascular leiomyoma of the nasal cavity. A 90-year-old woman visited our hospital because of recurrent epistaxis, and she was found in fiberscopy and computed tomography to have a well-defined spherical submucosal mass in the left nasal vestibule. The lesion showed low intensity in T1- and intermediate intensity in T2-weighted magnetic resonance imaging, with homogeneous intense gadolinium enhancement. The tumor was excised in a transnasal approach using an ultrasonic scalpel. Histopathological and immunohistochemical findings yielded a definitive diagnosis of venous vascular leiomyoma.
Vascular leiomyoma should be considered in the differential diagnosis of any well-circumscribed, hypervascular, soft-tissue mass arising in the submucosal tissue of the nasal cavity.
