No bony erosion was reported, and an infiltration of the lateral nasal cartilage could not be ruled out (Figure 1).
Contrast enhanced MRI, T1-weighted showing a single nodular lesion emanating from the lateral nasal wall and extending to the anterior face of the inferior nasal turbinate on the level of the piriform aperture without any sign of infiltrative growth.

A transnasal endoscopic tumor resection was performed under general anesthesia using a radiofrequency instrument (Ellman Surgitron) (Figure 3).
Histopathological examination: proliferation of smooth muscle cells permeated by thick-walled vessels with narrow lumens. No evidence of pleomorphism, mitosis, nuclear atypia, or necrosis. Hematoxylin and eosin stain; original magnification x100.
