[Idiopathic chylopericardium. Apropos of a new case. Review of the literature].

The authors report a new case of primary chylopericardium in an asymptomatic 26 year old male. In view of the negativity of the complementary etiological investigations a surgical subxiphoid window was performed and this confirmed the diagnosis. After failure of isolated evacuatory drainage, the patient was cured by pericardectomy.

[Malignant mediastinal embryoma. A case with pulmonary metastasis. Complete remission after chemotherapy].

Rapid increase in growth of a pulmonary metastasis following incomplete excision of a malignant mediastinal embryoma was treated by multiple chemotherapy combining platinum derivatives, actinomycin B, bleomycin, and vincaleucoblastin. Complete remission was obtained. These extremely rare tumours have a histological appearance close to that of testicular tumours.

[Pericardiac tamponade revealing a lympho-epithelial thymoma (author's transl)].

An inaugural pericardiac tamponade performed on a 39 years old man, reveals a lympho-epithelial thymoma. The anatomic diagnosis first suggested by the radiography after evacuation of the effusion, is confirmed by the swab taken during the retroxiphoidal drainage. A 57 Gray cobaltotherapy was then performed.
