title: [Endodermal pulmonary tumor resembling a fetal lung].
abstract: We report a case of a 56-year-old man who developed a flu-like syndrome associated with weight loss. Chest X-ray revealed a homogeneous round lesion of the lung with sharply defined margins in the central lobe. At pathology, the tumor was found to be an endodermal pulmonary tumor resembling a fetal lung. This uncommon tumor is generally a fortuitous chest X-ray finding seen as a rounded peripheral opacity. Diagnosis is based on pathology examination of the surgical specimen. Complementary investigations are not contributory. Unlike blastoma, a differential diagnosis, prognosis is generally good.
