[An unusual diagnosis of post-traumatic hemothorax]. / Hémothorax post-traumatique révélant un mésothéliome pleural malin.

We report the case of malignant pleural mesothelioma revealed by a post-traumatic hemothorax.

[Myxoid liposarcoma of the mediastinum: a case report]. / Liposarcome myxoïde du médiastin. A propos d'un cas.

We describe a mediastinal myxoid liposarcoma in a 47-year-old man who developed recurrent lung infection, treated by surgery associated with radiotherapy. The report of this case and a review of literature bring the authors to outline the epidemiological, clinical and therapeutic profile of this rare tumor.

[Nephrobronchial fistula: a case report]. / Fistule néphrobronchique. A propos d'un cas.

Nephrobronchial fistulas following pyonephrosis associated with urolithiasis are a rare occurrence. The possibility of severe problems arising during surgery should be taken into considerations; both the surgeon and the anesthetist should be fully informed of the specific risk factors involved. A favorable outcome mainly depends on the appropriate treatment and timely management of any thoracic complications. Although this rare pathology has been described in detail in the literature, the problems encountered during anesthesia and surgery have not been fully reported. This study therefore provides new data, as a case has been reported of a 38-year old female who underwent surgery for pyonephrosis; disease management and prognosis problems have been discussed.

[Mature teratome of the mediastinum]. / Tératome mature du médiastin.

STUDY AIM: The aim of this retrospective study was to report a series of 12 cases of mature teratoma of the mediastinum operated during a 10-year period in the same center. PATIENTS AND METHOD: From 1990 to 2000, 12 patients (7 females and 5 males with a mean age of 32 years) were operated for mature mediastinal teratoma. Chest pain was present in 10 cases; cough, dyspnea and septic episodes were present in 5 cases and X-ray detected the mediastinal tumor in 10 cases. CT scan showed a tumor with liquid and fatty components and calcifications in 5 out of 9 cases. Tumors were resected via a posterolateral thoracotomy in 11 cases and an anterior thoracotomy in one case, associated with pneumonectomy in 1 case, basal segmentectomy in 1 case and thymectomy in 1 case. RESULTS: There were no postoperative deaths. Morbidity included 2 phrenic nerve palsies, 1 pyothorax after pneumonectomy, 1 case of bleeding and 1 pleural effusion. No recurrences have been observed with a follow-up of 5 to 87 months. Nine of the 10 tumors reviewed by pathologist contained multiple tissue components and one only contained a single tissue. CONCLUSION: Mature teratomas are usually detected in young patients: they are usually located in the middle part of the anterior mediastinum and are only diagnosed by pathologic examination of the specimen. They have an excellent prognosis when tumor resection is complete and in the absence of immature tissue in the tumor.

[Inflammatory pseudotumor of the lung. An anatomoclinical study of a case report]. / Pseudotumeur inflammatoire du poumon. Etude anatomoclinique d'une observation.

One solitary pulmonary nodule was observed in a 47-year-old woman with history of right thigh liposarcoma 1 year before. Histological examination of the pulmonary specimen excluded liposarcoma metastasis and revealed an inflammatory pseudotumor. These unusual lesions with an excellent prognosis may exhibit, as in our case, atypical radiologic features and nuclear atypia, making the diagnosis difficult with malignancy.
