Colonic metastasis from lung cancer is rare and generally asymptomatic. Here, we report a case with lung adenocarcinoma that presented with acute abdominal pain due to intestinal obstruction caused by the metastatic colon tumor. The patient underwent emergency colonoscopy and the pathologic report was adenocarcinoma, which was the same as that for a bronchoscopic biopsy from a large lung mass. Immunohistochemistry was positive for thyroid transcription factor-1 and cytokeratin 7, and negative for cytokeratin 20 and caudal-related homeobox transcription factor 2 on both lung biopsy and colon surgical specimens. Accordingly, we used immunohistochemistry for thyroid transcription factor-1, cytokeratin 7, cytokeratin 20 and caudal-related homeobox transcription factor-2 to diagnose primary adenocarcinoma of the lung with colonic metastasis.

Symptomatic gastro-intestinal metastasis in lung cancer is extremely rare and only a few case reports have been published. Here, we report a case with lung adenocarcinoma that presented with acute abdominal pain, nausea and vomiting due to duodenum, jejunum, and colon obstruction by the gastro-intestinal metastasis. The patient underwent colonoscopy and the pathologic report was adenocarcinoma. When there are similar histologic findings in both colon and pulmonary lesion, the question is whether both lesions are primary cancer or the colon lesions are metastases from lung cancer. Microscopic examination of a conventional pathologic section was not sufficient to make this determination. Immunohistochemistry was positive for thyroid transcription factor-1 (TTF-1) and cytokeratin 7 (CK7), and negative for cytokeratin 20 (CK20) and caudal-related homeobox transcription factor-2 (CDX-2) on colon mucosa specimen. Accordingly, we used immunohistochemical marker for differential diagnosis of primary adenocarcinoma of the lung with gastro-intestinal metastasis.

Symptomatic gastrointestinal metastasis from lung malignancy is rarely reported. In this report, we present a case of lung adenocarcinoma with acute abdominal pain from small bowel perforation. The patient underwent small bowel resection and the final diagnosis was metastatic adenocarcinoma originating from lung. Immunohistochemistry was positive for thyroid transcription factor-1 and cytokeratin 7 (CK7), and negative for CK20. We present this rare case and briefly review the literature.
