Psammoma bodies or microcalcification in dissected lymph nodes in papillary thyroid carcinoma?

Many textbooks say psammoma bodies or calcification in dissected lymph nodes in papillary carcinoma of thyroid implies the possible tumor cell metastasis to the lymph nodes.

However there is no description mentioning the calcification or counting the lymph nodes with calcification as metastasized lymph nodes when staging the case. How do you deal with this matter? Do you count them or just ignore them?
