title: An unusual presentation of metastatic colon cancer to the lung.
abstract: A 75-year-old man with a history of resected colon carcinoma presented to his primary care physician because of a new onset of coughing. The patient had expectorated a small piece of solid tissue; pathologic examination of the tissue found it to be consistent with metastatic colon adenocarcinoma. After further work-up, a right upper lobectomy was performed. The surgical specimen removed during the lobectomy showed a tumor that was histologically identical to the patient's prior colonic primary tumor.
