Microscopic findings of the tumor. (a) Fibrous and cellular components of the tumor. (b) Fibrous component of the tumor. Spindle-shaped fibroblasts and mast cells (arrows) are scattered within the fibrous connective tissue. (c) Cellular sheet of the tumor. The sheet is composed of numerous Schwann cells and Meissner bodies. (d) High magnification of the Meissner bodies. Note the lamellar structures in these bodies.
