Abstract

A 71-year-old man was seen at the hospital because of a gingival tumor of the lower jaw. Following various examinations, he was found having triple cancer in which synchronous double cancer involving gingival cancer of the lower jaw and esophageal cancer was detected after surgery for gastric cancer. Significant lymph node swellings were noted in the left neck and right supraclavicular fossa. The gingival cancer was completely removed at a biopsy. After subtotal excision of the thoracic esophagus with esophageal reconstruction using the right hemicolon, the histopathological diagnosis of the esophageal cancer was squamous cell carcinoma localized in the submucosal layer. However, the pathological study of the appendix which was removed at the reconstruction surgery disclosed argyrophil carcinoid of it. The carcinoid was localized in the lamina propria mucosae, and the surgical stump was negative, so that argyrophil carcinoid which has favorable prognosis was diagnosed. No additional resection was thus performed. Thereafter we performed dissection of lymph nodes of the left neck and right supraclavicular fossa, followed by irradiation to the remnant lymph nodes in the right supraclavicular fossa. As of 14 months after the operation, no recurrence or new metastasis of esophageal cancer, gingival cancer and argyrophil carcinoid of the appendix has occurred, and no increasing tendency in the remnant lymph node swelling of the right supraclavicular fossa has been observed.
