Macroscopic findings and pathological examinations of lung tissue excised by wedge resection, confirming the positional relationships between the radiofrequency identification (RFID) marker and the target. A, Macroscopic findings. This lesion was finally diagnosed as a 5-mm minimally invasive adenocarcinoma, and it was removed with a deep margin of 12 mm (yellow arrow indicates tumor, white arrow indicates RFID marker). B-D, Microscopic findings showing that the lesion was a 5-mm minimally invasive adenocarcinoma with a 1-mm invasive component excised with a deep margin of 12 mm (red square indicates tumor, blue bar indicates deep margin).
