Surgical Treatment for Mediastinal Lymph Node Carcinoma of Unknown Primary
نویسندگان
چکیده
Carcinoma of unknown primary (CUP) is occasionally encountered in clinical oncology. Wide variation exists in CUP. We herein report a rare case of CUP of a mediastinal lymph node. A 61-year-old man with dermatomyositis was referred to our hospital for treatment of mediastinal adenopathy and gastric cancer. Biopsy of both lesions showed that they were histologically different from each other. Mediastinal lymphadenectomy and total gastrectomy were performed for a definitive diagnosis and radical cure. Pathological examination revealed two distinctly different disease processes. The patient underwent postoperative chemotherapy for residual gastric cancer. Twenty months postoperatively, he is alive with cancer. Although CUP usually has a poor prognosis, surgical treatment of metastatic mediastinal lymph node CUP is a feasible therapeutic option.
