However, by re-staining the original H&E sections with an anti-keratin antibody, the same 58 lymph node metastases were seen. Therefore, the three metastases emerged only in deeper sections which had been used for the immunohistochemical examination. It is suggested that the detection of micrometastases in lymph nodes may be improved by examining several sections at different levels rather than by immunohistochemical methods, even though these facilitate the observation of small groups of neoplastic cells.
