Figures 9 through 16 were inadvertantly printed in black and white. These figures should have been in color.

MPNST; dog No. 6. A few multinucleated giant cells with cytoplasmic PAS-positive globules (arrrow). HE. Bar = 20 µm

BPNST; dog No. 16. Anaplastic cells with abundant eosinophilic cytoplasm and large nuclei. HE. Bar = 25 µm.

MPNST; dog No. 2. Diffuse immunoreactivity for S-100 of the spindle-shaped tumor cells. Immunostaining for S-100. Bar = 40 µm.

BPNST; dog No. 16. Cytoplasmic and nuclear S-100-immunoreactivity of the epithelioid tumor cells. Immunostaining for S-100. Bar = 40 µm.

fMPNST; dog No. 4. NFGR-positive cells are focally distributed in round cells. Immunostaining for NGFR. Bar = 40 µm.

MPNST; dog No. 7. Scattered spindle neoplastic cells show cytoplasmic and membranous immunoreactivity for NGFR. Immunostaining for NGFR. Bar = 40 µm.

MPNST; dog. No. 1. Myoglobin-positive round cells in the right side. Almost granular cells (left side) are feebly positive or negative. Immunostaining for myoglobin. Bar = 50 µm.

BPNST; dog No. 16. Cytokeratin-positive neoplastic cells are scattered. Immunostaining for cytokeratin. Bar = 40 µm.
