Background. Pulmonary enteric adenocarcinoma is a rare histological type and is solid in most reports. Case. A 69-year-old man had been diagnosed as interstitial pneumonia at 55 years old. Follow-up computed tomography (CT) performed four years later showed a new reticular shadow in the right lower lobe. The shadow was enlarged on follow-up CT, so we performed wedge resection of the right lower lobe at 63 years old, but no malignancy was detected. Follow-up CT performed at 69 years old showed consolidation near the resected area, so he underwent right lower lobectomy. The histological findings of the tumor showed papillotubular adenocarcinoma that was suspected to be colorectal carcinoma. He underwent a thorough checkup of colorectal carcinoma, but no malignancy was detected. We ultimately diagnosed him with pulmonary enteric adenocarcinoma. Conclusion. An enlarging non-solid consolidation is difficult to distinguish from neoplastic disease and sometimes indicates the presence of pulmonary enteric adenocarcinoma, although this is rare.
