The sections show a tumour composed of spaced polygonal cells with moderately distinct cellular borders and moderate cytoplasm. The tumour cell nuclei are round and have round nucleoli seen with the 10x objective. Thin-walled blood vessels with bland endothelial cells are found within the tumour. No mitotic activity is apparent. Focal nuclear enlargement is present; however, no significant nuclear atypia is identified. | |||
