[A case of mediastinal adenocarcinoma of unknown origin presenting as a diffuse tumor shadow in the middle mediastinum].
We report a case of mediastinal adenocarcinoma of unknown origin presenting as a diffuse tumor shadow in the middle mediastinum. Cases of metastasis from cancer of unknown origin to hilar or mediastinal lymph nodes have often been reported. However, our case shows no round shadow indicating an enlarged lymph node, suggesting that the mediastinal adenocarcinoma originated from mediastinal tissue.
