title: A 72-Year-Old Woman With Previous Pulmonary Metastasis and New Peripheral Nodule.
abstract: A 72-year-old female nonsmoker was admitted to our Thoracic Surgery Unit in 2013 because of a lesion detected on chest CT scan during oncologic follow-up. Her medical history was significant for the development of a single pulmonary metastasis discovered 1 year after sigmoidectomy for colic adenocarcinoma. At that time, the patient was treated with six cycles of neoadjuvant chemotherapy followed by left lower lobectomy. Histologic examination demonstrated a pulmonary metastasis of colic adenocarcinoma with diffuse necrotic areas. The patient underwent subsequent adjuvant chemotherapy with capecitabine and was followed annually with biohumoral oncologic screening (carcinoembryonic antigen, carbohydrate antigen 19-9), chest-abdomen CT scan, and colonoscopy.
