[A case of rapidly growing inflammatory myofibroblastic tumor in the lung].

We report a case of a 28-year-old man with a dry cough and chest pain. Chest X-ray film showed a huge mass in the right lung field. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a huge mass which occupied most of the right thoracic cavity and invaded the superior vena cava, heart atrium and right pulmonary vein.

Amphiregulin attenuates bleomycin-induced pneumopathy in mice.

Amphiregulin, an EGF receptor (EGFR) ligand, is essential for epithelial development in various organs. A recent report suggested that amphiregulin acts as a protective factor in a liver injury model. Little is known about the roles of amphiregulin in lung injury and pulmonary fibrosis.
