We report the case of a 51-year-old woman with pulmonary adenocarcinoma with enteric differentiation (PAED) that is indistinguishable from metastatic colorectal carcinoma by immunohistochemistry as well as histology. A chest computed tomography scan revealed a 1cm nodule in the right upper lobe and a 3cm mass in the left lower lobe. Initial examination showed no evidence of any other tumor. She underwent partial resection of the right upper lobe and left lower lobectomy. Histopathological examination revealed that both tumors were composed of medium to large complex glands with central necrosis. The tumor cells were cuboidal to tall columnar with eosinophilc cytoplasm, oval nuclei, and brush-border. Immunohistochemical study yielded the following results: tumor cells were diffusely positive for cytokeratin (CK) 20 and CDX-2, and negative for CK7, thyroid transcription factor-1, and Napsin A. MUC2 was partially observed, while MUC5AC was not detected. These findings were strongly indicative of metastatic colorectal carcinoma. However, no primary colorectal cancer was detected in any clinical examination, including fluorine 18-labeled fluorodeoxyglucose-positron emission tomography scan and video capsule endoscopy, and she has not presented with any characteristic symptoms at any follow-up to date, approximately 4 years after operation. From all features, the final diagnosis was primary PAED, suggestive of multifocal primary lung cancer. So far, only 1 case of CK7-negative PAED has been reported. This is the second case of primary PAED resembling metastatic colorectal cancer morphologically and immunohistologically.
