Small solitary pulmonary metastasis detected before primary sigmoid colon cancer: report of a case.
We report the case of a 60-year-old woman referred to us after chest X-ray and mobile computed tomography screening detected an 8-mm nodule in right S2. Transbronchial aspiration cytology suggested a pulmonary metastasis from colorectal cancer. Therefore, we performed a colonoscopy and found a polypoid lesion, 2 cm in diameter, in the sigmoid colon. An analysis of a biopsy specimen from this polypoid lesion confirmed adenocarcinoma. Surgical resection of the primary sigmoid colon cancer was subsequently performed, followed 4 weeks later by a right S2 segmentectomy to remove the lung metastasis. The patient is currently well without any clinical signs of recurrence, 44 months after her operation.
