dysembryomes du mediastin [a propos de 30 cas operes]

ABSTRACT

From 1965 still 1980 thirty dysembryoma out of 100 surgical tumors of mediastinum operated by the members of the thoracic surgery Service [Hospital Avicenne] are analysed and compared to the donnees of literature. The bronchogenic cysts prevail with 12 cases out of 22 homoplastic dysembryoma. They are followed by the coelomic cysts. Out of 8 heteroplastic dysembryoma there are six dermoid cysts and 2 non malignant teratoma. In this series in which there is neither new borns non infants, the seven children who are aged less than 15 years old had specially bronchogenic cysts [5/7]. The coelom cysts are seen in adults only. The 30 dysembryoma are benign, the prognosis good. However, if the tumor resection had been complete in 23 cases, it was associated to 7 cases of partiel lung resection
