Figure 8: Histologic section of a cheek mass in a goat

The neoplastic spindle cells (arrowheads) are embedded within light blue mucinous matrix material (*), mimicking that seen in the cytologic smears. The neoplastic cells have indistinct borders; a moderate amount of pale, eosinophilic cytoplasm and oval nuclei, with finely stippled chromatin and a single nucleolus. Anisocytosis and anisokaryosis are mild, with few mitotic figures Some tumor cells are embedded in collagen (arrowhead to the left) with normal dermal collagen on the outer aspects of the mass (arrow) (H&E stain, 50x objective).
