Pulmonary tumor embolism syndrome is a rare phenomenon that can occur in patients who have an occult neoplasm that metastasizes. We describe a case of an elderly woman with an undiagnosed colon cancer who suffered from respiratory distress and compromised pulmonary blood flow from micrometastasis in the pulmonary arteries.

Marks, P. (1974). Thorax, 29, 248-251. Multiple thoracotomy for metastatic pulmonary neoplasm. Surgical excision of solitary, metastatic, malignant lesions of the lung is reported as of benefit in certain cases in which the primary tumour apparently has been completely removed and in which there is no evidence of further metastatic spread. It has been shown that in a few instances survival for ...

Extension of primary lung tumors into the left atrium via pulmonary veins is a well-documented phenomenon. Peripheral arterial embolism and cerebral embolism originating from a primary lung neoplasm are rare events. We report a case of simultaneous acute bilateral lower limb ischemia, bilateral renal infarction, splenic infarction and cerebral infarction as a result of multiple emboli originati...

Papillary adenocarcinoma of the lungs is the most common primary lung adenocarcinoma, with the feature of papillary-like structure formation by cells. A dog was presented with the primary complaint of vomiting, hyporexia and increased respiratory effort. Thoracic radiography revealed increased soft tissue radiopacity of the right cranial lung lobe suggestive of possible consolidation or collaps...

Primary pulmonary synovial sarcoma is an extremely rare tumor with an unknown cause. The diagnosis is established after other primary lung malignancies or metastatic extrathoracic sarcoma have been excluded. We report the case of a 69-year-old man who presented with a well-defined mass in the right upper lobe on a chest X-ray. A video-assisted thoracoscopic surgery (VATS) right upper lobectomy ...

Background. Primary pulmonary artery sarcomas are very rare and their histologic type, called leiomyosarcoma, is even rarer. Case Report. A 64-year-old woman presented with progressive weakness, fatigue, malaise, and dyspnea, and a marked elevation of pulmonary artery pressure was admitted. She was initially diagnosed with chronic pulmonary thromboembolism and chest computed tomography (CT) sca...

The differential diagnosis of new-onset pulmonary infiltrates during adjuvant therapy in a cancer patient is challenging. Opportunistic infections, pulmonary drug-induced toxicity and metastatic dissemination of the underlying cancer are the most common causes. However, although infrequent, the development of a second primary pulmonary neoplasia should be taken into account. We present the clin...

We report a case of pulmonary sarcoidosis, which initially presented as a left apical infiltrate. The later course mimicked a pulmonary neoplasm, with left upper lobe atelectasis secondary to bronchial stenosis, resulting from both endobronchial sarcoidosis and extrinsic compression by enlarged lymph nodes. Extrinsic pressure from sarcoid nodes on the left main pulmonary artery and recurrent la...
