Asymptomatically Synchronous Esophageal Cancer Incidentally Detected by F-18 Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography in a Prostate Cancer Patient

The emergence of a second primary cancer is usually one of the leading causes of therapeutic failure in patients with known malignancies. Detection of a second primary cancer may reduce the corresponding morbidity and mortality, especially in patients without the symptoms that are illustrative of a second primary malignancy. Here, we report a rare coincidence of an asymptomatically synchronous esophageal cancer incidentally detected by F-18 fluorodeoxyglucose positron emission tomography/computed tomography in a 65-year-old prostate cancer patient. The treatment strategy was accordingly changed to esophagectomy with colon interposition and jejunostomy after neoadjuvant chemotherapy and radiotherapy.
