Figure 1: Soft tissue perineurioma. (a) Circumscribed tumor comprising spindle shaped cells in whorls and fascicles (H and E, × 100). Inset: Perivascular arrangement of spindle cells with slender nuclei (H and E, × 400). (b) Uniform spindly cells in whorls (onion bulb-like) and lamellar arrangement (H and E, × 200). Inset: Spindle cells with slender, benign nuclei and elongated cytoplasmic processes (H and E, × 400). (c) Diffuse EMA positivity. DAB × 200. Inset: Cytoplasmic and membranous EMA positivity. (DAB × 400). (d) Focal S100-P positivity within scattered polygonal cells. (DAB × 200). (e) Low MIB1. (DAB × 400).
