Tracheal polypoid combined small cell lung cancer (C‐SCLC): A case report

Abstract

Abstract Small cell lung cancer (SCLC) is an aggressive malignancy with a poor prognosis that accounts for 10% of all cases of clinical lung cancer. Due to its high growth fraction and rapid doubling time it is usually diagnosed as extensive local or metastatic disease in 60%–70% of cases. Combined small cell lung cancer (C‐SCLC) is a relatively rare subtype of SCLC and is defined as SCLC combined with any elements of non‐small cell lung cancer (NSCLC). Clinical presentation of SCLC as an isolated pedunculated endotracheal lesion is an especially rare occurrence. Here, we report for the first time the occurrence of a C‐SCLC as a polypoid tumor of the trachea diagnosed in an 80‐year‐old woman admitted to the emergency department with a principal complaint of cough and wheezing.
