Pulmonary artery sarcomas are rare, difficult-to-diagnose tumors that frequently mimic chronic pulmonary thromboembolism. We report the cases of two female patients with clinical signs of dyspnea and lung masses associated with pulmonary artery filling defects on chest CT angiography. We performed 18F-fluorodeoxyglucose positron emission tomography, which revealed increased radiotracer uptake i...

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare pulmonary disorder characterised by a proliferation of neuroendocrine cells within the lung. It is believed that a minority of the patients with DIPNECH can develop carcinoid tumors. Here, we report two new cases of DIPNECH with coexisting carcinoid tumors.

A 67-year-old male was admitted to our hospital because of pulmonary metastasis from colo-rectal cancer. Chest computed tomography revealed three tumor shadows just under the pleura. Because the tumors were adjacent to each other, we performed an en bloc pulmonary resection. Pathologically, two of the tumors were diagnosed as pulmonary metastases; the remaining tumor, however, was diagnosed as ...

BACKGROUND Pulmonary metastases are often found in advanced malignancies. Urogenital malignancies originating from kidney, prostate, testes, and bladder all metastasize preferentially to the lungs. OBJECTIVES This retrospective study aimed to evaluate the results of pulmonary and chest wall metastasectomy in patients with primary urogenital Tumors. PATIENTS AND METHODS The patients who unde...

The spectrum of pulmonary neuroendocrine cell proliferation ranges from reactive hyperplasia to small cell carcinoma and includes diffuse idiopathic pulmonary neuroendocrine cell hyperplasia. A case is reported and features of this disease are described according to the published evidence. The entity was first included in the WHO classification of tumors in 1999 and is considered a preneoplasti...

Medical College, Kolkata, West Bengal, India Mobile: +919433383080 Email:[email protected] Introduction Unusual tracheobronchial tumors represent 4% to 6% of all lung tumors (benign and malignant).1 Adenoid cystic carcinoma (ACC) accounts for less than 0.2% of all lung tumors.2 Pulmonary ACC usually arise ...

PURPOSE This study was performed to evaluate the effectiveness of conventional chest radiography, carcinoembrionic antigen (CEA) level and abdominal computed tomography (CT) or chest CT for early detection of pulmonary metastasis after a curative resection of colorectal cancer. METHODS We retrospectively reviewed 84 cases of pulmonary metastasis from a group of colorectal cancer patients who ...

Purpose: To determine the clinical course and outcome of patients undergoing pulmonary resection for metastatic endocrine tumors. Methods: Retrospective review of 47 patients with known endocrine tumors and pulmonary metastases who were evaluated for surgical resection between 1975 and 1996. Results: Tumors evaluated included the following: carcinoid (16), thyroid (12), pancreatic adenocar¬ cin...

Primary pulmonary lymphoma (PCL) is rare and represents only 0.5-1% of the malignant lung tumour. Pulmonary MALT most common histological aspect. The pathophysiological mechanism remains poorly known, unlike other locations lymphoma, no pathogen has so far been associated with localization disease. It characterized by slow evolution atypical clinical presentation which delays diagnosis. form «...
