However, up to 10% of these patients relapse postoperatively.

This pattern has been described in various organs. However, tumor cells with micropapillary pattern of lung adenocarcinoma are more often seen to float within alveolar spaces (aerogenous(More)

To avoid the complications of internal pneumatic stabilization for flail chest, we performed stabilization of the chest wall with a metal bar using the Nuss procedure. Here, we used a highly elastic lightweight biocompatible titanium alloy Chest Way (Solve Corporation, Kanagawa, Japan), enabling magnetic resonance imaging. The patient was a 37-year-old man(More)
Localized malignant pleural mesothelioma (LMPM) is a rare tumor; previously only 52 cases have been reported in the English literature. This type of tumor should be distinguished from diffuse malignant pleural mesothelioma, because a good outcome may be obtained by surgical resection. We report a case of LMPM which grew rapidly within 1 year. Surgical(More)
