Abstract
Spontaneous expectoration of the tissue fragments in primary lung carcinoma is an
extremely unusual event. 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.
