식도, 위, 폐 그리고 구강에 동시 발생한 다발성 원발암

A 65-year-old-male had a mass in the oral cavity, and this was ultimately determined to be squamous cell carcinoma and he underwent wide excision for it. Postoperatively, he underwent the staging work up; this showed that he had other cancers in the esophagus, stomach and lung. We performed a curative resection of all the lesions simultaneously. We report here on a case of synchronous multiple cancers of the esophagus, stomach, lung and oral cavity.
