The TILs score is limited to lymphocytes and plasmacells. Don’t score neutrophils as TILs!
Presence of siderophages suggests prior biopsy site. Do not score TILs in areas of previous biopsy or surgery
Do not include lymphoid aggregates in TILs count and do not score TILs around DCIS
Do NOT score TILs on tissue with fixation artefacts! Fix well your tissues!
