1/3. cardiac tamponade originating from primary gastric signet ring cell carcinoma.A 45-year-old man with dry cough and dyspnea was referred by a medical practitioner for evaluation of heart failure on February 10, 1996. Chest X-ray revealed increased cardiothoracic ratio, and ultrasonographic echocardiography disclosed massive pericardial effusion with right ventricular collapse. cardiac tamponade was diagnosed and pericardiocentesis was performed. Ten days after admission, the pleural effusion had become more pronounced, and thoracocentesis was performed. carcinoembryonic antigen level was elevated in both the pericardial and pleural effusion, and cytology implicated adenocarcinoma, which suggested malignant effusion. Endoscopic study disclosed gastric cancer in the posterior wall of the upper body, and the histopathological diagnosis was signet-ring cell carcinoma. The patient died of respiratory failure on May 2, 1996, and autopsy was performed. The final diagnosis was gastric cancer with pulmonary lymphangitis, pericarditis, and pleuritis carcinomatosa, accompanied by enlargement of mediastinal and paraaortic lymph nodes. Interestingly, the primary signet-ring cell carcinoma of the stomach was situated mostly in the mucosa. Deep in the submucosal region, there was prominent invasion of the intralymphatic vessels, without direct destruction of the mucosa muscularis.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/3. Mediastinal cystic lymphangioma: is resection always necessary?Mediastinal cystic lymphangiomas are rare tumours. Usually asymptomatic, they can be complicated by a chylopericardium or/and chylothorax. We report a case of a left lesion infiltrating through the supra-aortic vessels complicated with a iatrogenic left chylothorax managed by bilateral video-assisted thoracoscopy at the same time. First, on the right, the chylous inflow was stopped by suturing the thoracic duct; then, on the left, a fenestration was done to confirm the diagnosis and treat the lesion while preserving the adjacent structures.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/3. Diffuse pulmonary angiomatosis.A six year old girl with diffuse pulmonary angiomatosis presented with haemoptysis and diffuse interstitial changes with bilateral pleural effusions on the chest radiograph. The lung lesion as seen on biopsy specimens (and confirmed at necropsy) consisted of bloodless, thin walled, endothelium lined channels, affecting the interstitial septae, pleura, bronchi, and adventitia of large vessels. There was no response to oral corticosteroids or a trial of cyclosphamide. This lesion may be an example of an angiogenic disease.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
