Expectoration of tumor fragments is a significant event that should not be ignored as it serves itself as a noninvasive tool to diagnose underlying malignancy if such samples are immediately preserved and subjected to histopathological examination. More so, expectoration of a large-sized fragment may provide substantial relief from the breathlessness. Reported here is the case of a middle-aged male patient with adenocarcinoma in the right lung, and mass extended up to trachea, who spontaneously coughed out pieces of tumor tissue.<\/jats:p>","DOI":"10.4103\/ajm.ajm_97_20","type":"journal-article","created":{"date-parts":[[2021,1,5]],"date-time":"2021-01-05T10:15:13Z","timestamp":1609841713000},"page":"46-48","source":"Crossref","is-referenced-by-count":4,"title":["Spontaneous expectoration of tumor tissue in primary adenocarcinoma lung"],"prefix":"10.1055","volume":"11","author":[{"given":"Ramakant","family":"Dixit","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine, J.
