Abstract

According to the World Health Organization 2015 classification of Thoracic tumors, updated to 2021, the adenocarcinoma group includes the following subtypes: (1) Minimally invasive adenocarcinoma (MIA); (2) Invasive non-mucinous adenocarcinoma (INMA); (3) Invasive mucinous adenocarcinoma (IMA); (4) Colloid adenocarcinoma (CA); (5) Fetal adenocarcinoma (FA); (6) Enteric-type adenocarcinoma (EA). In which, Enteric-type Adenocarcinoma (EA) or Pulmonary Enteric Adenocarcinoma (PEAC) is said to be very rare, with high malignancy, rapid progression, very difficult to treat. Diagnosis of lung adenocarcinoma is generally based on pathological findings; Subtype diagnoses require immunohistochemistry support. We present a rare case of PEAC with quite special images: large tumor in upper lobe of left lung, large lymph node masses around trachea, main and inferior bronchus of Carina; All of the above abnormalities had internal calcifications. There are also many other nodules (atypically secondary) of the ipsilateral and contralateral lung. Initially, the case was diagnosed and monitored for pulmonary tuberculosis; The definitive diagnosis of PEAC by histopathology and immunohistochemistry was obtained by transthoracic biopsy under computed tomography guidance.
