Hematoxylin and eosin (H&E) staining of the lung biopsy specimen of four cases. The H＆E staining of H81, whose biopsy specimen obtained on 29 September 2016 (a) and 29 July 2019 (b), revealed a moderately differentiated squamous cell carcinoma (SCC) with necrosis, where numerous lymphocytes also infiltrated. The H＆E staining of he_78, whose biopsy specimen obtained on 23 May 2019 (c), indicated a nonsmall cell lung cancer (NSCLC) with few infiltrating lymphocytes, while that obtained on 28 June 2019 (d) revealed a necrotic tissue without any tumor cell or lymphocyte. The H＆E staining of he_57, whose biopsy specimen obtained on 18 April 2019 (e) and 28 May 2019 (f), demonstrated a tissue of small cell lung cancer (SCLC) (e) and spindle cell poorly differentiated carcinoma (f), both of which were without lymphocyte infiltration. The H＆E staining of he_80, whose biopsy specimen obtained on 21 May 2019 (g) and 29 July 2019 (h), displayed a micropapillary lung adenocarcinoma (g) and ductal type adenocarcinoma (h), both of which were with little lymphocyte infiltration.
