title: [Experience of long term survival in a case with surgery for cancer metastasis to brain and mediastinal lymph node from unknown primary site].
abstract: We report a rare case of metastatic brain and lymph node carcinoma of unknown primary origin. A 68-year-old man had been followed up after resection of brain metastasis in right parietooccipital region without suspicious primary site. Seventy-eight months after the resection, a mediastinal lymph node (#2R) of 15 mm in diameter was detected by computed tomography (CT) and was surgically removed. The histological diagnosis was poorly differentiated adenocarcinoma resembling lymphoepithelial carcinoma, which was similar to the histology of the previously resected brain tumor. This patient is alive without recurrence and apparent primary site at 24 months after lymph node resection.
