title: [A rare pulmonary tumor: pneumoblastoma. Apropos of a case and review of the literature].
abstract: A case of pneumoblastoma concerning a 33 year old man, incidentally discovered on a systematic chest X Ray, is reported. The radiologic findings include a voluminous and peripherical mass with necrotic zones. The pathologic findings in optic microscopy and the special technics consist in the three cellular contingents which form the pneumoblastoma: clusters of indifferentiated cells, epithelial cells and spindle cells. All the features show clearly a blastomatic character very similar to a foetal lung which allows to differentiate the pulmonary blastoma from carcinosarcoma. The authors, through a review of the literature, demonstrate the rarity (less than 100 cases reported), the malignant evolution which metastasis and the age (strong majority of adults) which characterize this pathology.
