[Hamartochondroma: An unusual cause of endobronchial obstruction in smoking patients]. / L'hamartochondrome : cause inhabituelle d'obstacle endobronchique chez des patients fumeurs.

Endobronchial hamartochondroma is a rare benign tumor which differs from the parenchymal form in its symptomatology and also by its treatment which should be as conservative as possible. The endobronchial location is exceptional. Here we present the cases of two patients with endobronchial hamartochondroma associated with clinical manifestation, chest pain and repeated pulmonary infections, respectively. The diagnosis was made after performing a CT-scan, a PET-SCAN and histological analysis. After discussion in a multidisciplinary staff meeting, conservative treatment was chosen in both cases.

[An exceptional case of tricuspid infective endocarditis due to Bartonella henseale revealed by an old pulmonary embolism]. / Un cas exceptionnel d'endocardite infectieuse tricuspide à Bartonella henselae révélée par une embolie pulmonaire « vieillie ¼.

We report a case of blood culture-negative tricuspid infective endocarditis revealed after tick bite by repeated pulmonary infection during one year due to septic pulmonary emboli in a 67-year-old farmer woman. Tricuspid vegetation and pulmonary emboli are calcified. Lyme serology is negative. Serologic test and PCR analysis are positive to Bartonella henselae. The evolution is favorable after antibiotic and anticoagulant treatment. Infective endocarditis due to B. henselae is an exceptional complication of cat scratch disease. You have to think about in case of blood culture-negative endocarditis with calcified valvular lesions even without cat bite, tick seems to be vector of the bacteria.

[Perforation of the nasal septum: a rare complication of bevacizumab]. / Perforation de la cloison nasale : une complication rare du bévacizumab.

INTRODUCTION: Neovascularisation is a hallmark of cancer. Vascular endothelial growth factor (VEGF) is directly involved in the regulation of this tumoural neoangiogenesis, especially in lung cancer. Bevacizumab is a humanized monoclonal antibody targeting VEGF that is commonly used in thoracic oncology. Among the side effects, perforation of the nasal septum is rare. CASE REPORT: We report the case of a 50-year-old woman with adenocarcinoma of the right upper lobe, immediately metastatic, treated with five cycles of chemotherapy (cisplatin, gemcitabine, bevacizumab). She developed a perforation of the nasal septum after the third injection of bevacizumab given as monotherapy during the maintenance phase. CONCLUSIONS: This is, to our knowledge, the first description of this complication in the course of treatment of bronchial carcinoma. Its management is purely symptomatic. The action to be taken in using bevacizumab is not fully codified.

[Endoscopic management of broncho-pleural fistula in a patient with acute respiratory distress syndrome after pneumonectomy]. / Prise en charge endoscopique d'une fistule bronchopleurale chez un patient en syndrome de détresse respiratoire aiguë après pneumonectomie.

We report the management of endobronchial a patient admitted to the ICU for respiratory distress in the consequences of an surgical recovery of his left pneumonectomy complicated by bronchopleural fistula as part of a bronchial carcinoma non-small cell type adenocarcinoma. Endobronchial treatment by gluing of the fistula may be an alternative to surgery. We discuss its indication in the treatment of bronchial fistula.

[Cardiac extension of a non-Hodgkin lymphoma revealed by an atrial flutter]. / Flutter atrial révélateur de l'extension cardiaque d'un lymphome malin non hodgkinien.

Primary or secondary cardiac lymphomas are not frequent. Their clinical expression is unusual and the diagnosis is rarely made during the patient's life. Our case report, which is a slow atrial flutter with a pericardial effusion, is an uncommon discovery mode for a malignant lymphoma. Their diagnosis and the mechanism of the arythmia were allowed by non-invasive cardiac imagery (transesophageal echography and magnetic resonance imaging), which showed a tumour-like infiltration of the right atrium, of the right ventricle posterior wall, and of the atrioventricular junction. The diagnosis of a high grade B cell malignant non-hodgkin lymphoma, involving the bone marrow, the liver and the kidneys was made by biopsies of lymph nodes, histological analysis of the bone marrow, and a body CT scan. Throughout the first chemotherapy sequence, we observed a spontaneous return to a sinusal rhythm, and the cardiac MRI showed a regression of the myocardial infiltration and of the pericardial effusion; moreover, the patient's state improved and the peripheral lymph nodes shrank back to a normal size. However, the patient passed away, due to neurological complications 13 months after the diagnosis of lymphoma, without recurrence of cardiac involvement.

[A rare cause of stridor in a 59 year old woman in intensive care]. / Stridor d'étiologie rare en post-réanimation chez une patiente de 59 ans.

INTRODUCTION: Stridor in the post extubation period occurs frequently and is most commonly caused by laryngeal oedema. During this period, the trachea can also be obstructed by pseudomembranes. CASE REPORT: We report the case of a 59 year old woman who required re-intubation, 15 days after extubation because of the acute onset of severe respiratory distress secondary to pseudomembranes in her trachea. CONCLUSION: It is essential that physicians who care for patients during the post extubation period are aware of this severe and life threatening cause of stridor. Definitive treatment with the rigid bronchoscope allows for rapid recanalisation of the airway.

[Spontaneous pneumomediastinum in young adults: a benign clinical entity]. / Pneumomédiastin spontané du jeune adulte: une entité clinique bénigne.

INTRODUCTION: Spontaneous pneumomediastinum is a little known cause of chest pain in young adults. The prognosis is invariably good. CASE REPORT: The authors report two cases of spontaneous pneumomediastinum with different aetiologies developing in young adults. The first occurred during strenuous sport and the second during an asthma attack. CONCLUSION: The discussion stresses the frequency of this condition in young men, its pathogenesis and natural history. In particular the authors draw on the current scientific data to explain the absence of predisposing factors and the extreme rarity of relapse of this benign disorder. Poor acquaintance with this clinical entity may lead to unnecessary diagnostic and therapeutic actions. The authors suggest a guideline for the management of this disorder.
