A case report of pulmonary combined small cell carcinoma with enteric adenocarcinoma.

ABSTRACT:

Background

Combined small cell lung cancer (CSCLC) is rarely reported, which accounting for only 2% to 5% of all lung cancers. And enteric adenocarcinoma is also a rare subtype of non-small cell lung cancer (NSCLC) whose histomorphology is very similar to lung metastatic colorectal cancer.

Case description

We report a case with both small cell lung cancer (SCLC) and enteric adenocarcinoma for the first time. The patient was admitted to our hospital due to the left lung mass after a routine examination. She underwent computed tomography scan and needle biopsy, which showed the tumor consisted of two different components (70% SCLC and 30% enteric adenocarcinoma). The mixed density nodules were also observed in the right lung's lower lobe, and positron emission tomography-compu
