case_images: A) The external physical examination revealed a 2 cm-sized mass on the nasal dorsum. B) T1-weighted MRI shows a 2.2x1.9x1.6 cm-sized, hypointense, well-circumscribed, nodular solid mass on the tip of the nose.

case_images: A 2x2 cm firm, palpable lump on the nasal dorsum was identified during the physical examination (Figure 1). On magnetic resonance imaging, a 2.2x1.9x1.6 cm-sized, well-circumscribed solid nodular lesion that was hypointense in T1 and T2A was seen on the tip of the nose and extended to the right alar wing (Figure 1).
case_images: In the histopathological evaluation of the specimen, A) low power magnification shows a highly fibrotic hypocellular lesion (H&E 100x), B) high power magnification shows the lesion is composed of spindle cells and collagen bundles arranged in a fascicular and whorled pattern, and no neuropil or ganglion cells can be seen (H&E 200x). The glial tissue that was entrapped with fibrovascular stroma was positive for C) S100 and D) GFAP.

case_images: Microscopically, a highly fibrotic hypocellular lesion was composed primarily of spindle cells and collagen bundles organized in a fascicular pattern (Figure 2). There were no apparent neuropil or ganglion cells with H&E (Figure 2). The glial tissue entrapped by a fibrovascular stroma was immunohistochemically positive for S100 (Figure 2) and GFAP (Figure 2), but negative for CD34 and EMA.
