case_images: A nasal examination revealed an external enlargement on the right nasal ala, which extended from the right lower lateral cartilage to the right upper lateral cartilage (Figure 1).
case_images: Computed tomography demonstrating isolated poorly defined soft tissue swelling within the right-sided lateral nasal wall anteriorly. There was a mild heterogeneous contrast enhancement but no clear expansion to surrounding structures.

case_images: There was a mild heterogeneous contrast enhancement but no clear expansion to surrounding structures (Figure 2).
case_images: Sagittal (a) and axial (b) magnetic resonance imaging confirmed the presence of an oval lesion (arrows) measuring about 0.5 x 0.7 cm with isointense signals in all pulse sequences, with homogenous postcontrast enhancement, clear surrounding fat planes with no invasion to nasal septum or other adjacent structures.

case_images: The tumor was surrounded by distinct fat planes, with no invasion of the nasal septum or any nearby structures (Figure 3).
case_images: The mass was successively dissected from the surrounding structures and excised completely.

case_images: The mass was meticulously dissected from the surrounding structures and completely excised (Figure 4).
case_images: Histopathology of the specimen revealed (a) a well-circumscribed spindle cell neoplasm, showing vague storiform pattern with collagenized stroma. (b) Cells have indistinct cytoplasm and wavy nuclei. (c, d) Mild pleomorphism with no increase in mitosis or necrosis.
