Non-Hodgkin's lymphoma (NHL) occurring as a synchronous malignancy with chronic myelogenous leukemia (CML) is rare. To our knowledge, this is the first case reported of a patient who developed mantle cell lymphoma (MCL) after therapy with imatinib mesylate for CML. After a 3-year history of CML, the patient developed a lymphocytosis associated with diarrhea, anorexia, and weight loss. Imaging studies revealed abdominal adenopathy and extensive lymphomatous infiltration of the liver, stomach, pancreas, and kidneys. Flow cytometric and cytogenetic studies were consistent with MCL. Fluorescence in situ hybridization (FISH) of the bone marrow revealed a genetically distinct lymphoid neoplasm rather than an extramedullary blast crisis of CML. The development of lung cancer, prostate cancer, CML and MCL in this patient suggests a genetic predisposition, although other factors, including environmental exposures and therapy with imatinib mesylate could have had a contributory or synergistic role in the development of MCL.

Lung cancer is the most frequently encountered cancer in humans and commonly metastasizes to brain and bone. Metastasis to the clivus is very rare and there have been no previous reports. A 51-year-old woman was admitted to our hospital complaining of headache, and left shoulder, arm and back pain. The chest X-ray showed a left paracardiac mass measuring 4x4 cm in diameter and the thorax computed tomographic examination revealed a 4x4 cm mass in the left lower lobe, left hilar and mediastinal lymphadenopathy, and multiple lytic lesions in the thoracic vertebral bodies. Head magnetic resonance imaging showed a mass in the clivus with bony destruction. Bronchoscopic examination revealed an exophytic endobronchial lesion in the left lower bronchus lumen and a biopsy was taken from this lesion. The histopathological diagnosis was "poorly differentiated squamous cell carcinoma". A punch biopsy was taken from the clivus via the transnasal-transphenoidal route. Histopathological findings of this biopsy were similar to the primary site tumor. We report a rare case of clivus metastasis from squamous cell lung cancer.

A 54-year-old woman with a history of fatigue and shortness of breath was found to have a pericardial effusion and mild mediastinal lymphadenopathy. Video-assisted pericardioscopy revealed thickened pericardium studded with multiple nodules. Histologically the tumor was diagnosed as papillary adenocarcinoma. The site of the primary tumor could not be identified. As lung cancer is one of the most frequent causes of pericardial metastases the patient was treated with cisplatin and vinblastin. Following 5 courses of chemotherapy--given over a 4 month period--the amount of pericardial effusion and pericardial thickness did not change. The material from pericardial biopsy was reexamined and positive immunostaining for calretinine was found. The final diagnosis was primary pericardial mesothelioma of epithelioid type. Palliative radiotherapy of mediastinum was planned but the patient deteriorated and died due to disease progression with venous thrombosis and superior vena cava syndrome. The case illustrates the difficulties in establishing diagnosis of primary pericardial mesothelioma which is a rare tumor with poor prognosis.

Mediastinal lymph node biopsy plays a fundamental role in diagnosis, staging and management of lung cancer. We describe a novel method of using the video-mediastinoscope for concurrent cervical mediastinotomy and anterior mediastinoscopy. We have performed five concurrent procedures using this system in the last 14 months. In four cases, we assessed the aorto-pulmonary (A-P) window lymph nodes. In the fifth case, we performed a cervical mediastinoscopy for para-tracheal and sub-carinal lymphadenopathy followed by an anterior videomediastinotomy, video assisted intrapericardial assessment, direct tumour sampling and A-P window lymph nodal biopsies. Due to the excellent visualisation afforded by the Videomediastinoscope, we were able to avoid an open procedure in all cases. We believe that this represents a major benefit of the videomediastinoscope in select cases.

A 67-year-old man presented at our hospital with suspected right lung cancer with mediastinal and hilar lymphadenopathy. Although swollen lymph nodes had first been noted 8 years previously, only minimal enlargement had occurred over the intervening period. Video-assisted thoracoscopic biopsy of the pulmonary lesion and the mediastinal and hilar lymph nodes was performed. Final histopathological diagnosis was a poorly differentiated adenocarcinoma of the lung staged as T1NOMO and a coexistent localized hyaline-vascular type of Castleman disease. Right upper lobectomy was performed and postoperative histological findings suggested that this was likely to be curative. This is a rare case of coexistence of lung cancer and Castleman disease, illustrating the difficulties in distinguishing lymph node metastasis from other pulmonary diseases.

Helical CT, and the newest technological development, multislice CT (multidetector CT: MDCT), have revolutionized the diagnostic approach to diseases of the chest including lung cancer. There are several factors that contribute to the important role of multislice CT scanning of the chest: (1) data acquisition is so rapid that the scanning of the entire lung can be performed during a single breath-hold period; (2) continuous acquisition of thin slices allows the improvement of the image quality of multiplanar reconstruction of thoracic abnormalities; (3) MDCT may help reduce the radiation dose, so that, compared to conventional or single-slice helical CT, the radiation dose is lowered with comparable image quality. The advantages of MDCT include both improved nodule detection and nodule characterization on lung cancer screening programs, because the entire lung can be scanned with thin slice in a single breath-hold without an intersection gap. In the evaluation of lung cancer, MDCT will allow improved detection of pleural dissemination and hilar lymph node adenopathy because of the continuous and narrow scan collimation.

Tonsillar metastasis from neoplasms, including lung cancer, are extremely rare, and the prognosis for patients with tonsillar metastases is rather poor. We herein describe a case of long-term survival following radiation for lingual tonsillar metastasis from a bronchial adenocarcinoma. A 39-year-old male was diagnosed with adenocarcinoma of the right lung and was surgically treated. Four months after surgery, a mass arising from the lingual tonsil was noted at the root of the tongue and was pathologically diagnosed as metastasis from lung cancer. In addition, a computed tomography scan revealed a jugular lymphadenopathy, which was considered to be a metastasis from the tonsillar tumor. The tonsillar mass and jugular lymphadenopathy disappeared after external radiotherapy (50 Gy). The patient is alive without recurrence more than 8 years after treatment for tonsillar metastasis. This is the first report of successfully treated tonsillar metastasis from a malignant tumor.

After discovering a lung cancer without extrathoracic metastases, the preoperative mediastinal check-up is of great importance to determine the patients operability. The 78% specificity of activity measuring FDG in a PET examination is clearly insufficient to avoid a biopsy of the incriminated lymph nodes. The investigation of a suspected malignant adenopathy justifies a complete examination by mediastinoscopy or-tomy, which are considered gold standards. The transbronchial fine needle aspiration guided by ultrasound (EBUS-TBNA) constitutes the recent evolution of TBNA, method known for 20 years now but underused. Depending on the operators skill, this new procedure needs a learning curve before being able to replace mediastinoscopy.

Endobronchial metastases (EBM) from extrapulmonary malignant tumors are rare. The most common extrathoracic malignancies associated with EBM are breast, renal and colorectal carcinomas. In this study, we aimed to evaluate the clinical, radiographic and bronchoscopic aspects of patients with EBM who were diagnosed between 1992 and 2002. Data about patients' clinical conditions, symptoms, radiographic and endoscopic findings, and histopathological examination results were investigated. EBM was defined as bronchoscopically visible lesions histopathologically identical to the primary tumor in patients with extrapulmonary malignancies. We found 15 cases with EBM. Primary tumors included breast (3), colorectal (3), and renal (2) carcinomas; Malignant Melanoma (2); synovial sarcoma (1), ampulla of Vater adenocarcinoma (1), pheochromocytoma (1), hypernephroma (1), and Hodgkin's Disease (1). The most common symptoms were dyspnea (80%), cough (66.6%) and hemoptysis (33.3%). Multiple (40%) or single (13.3%) pulmonary nodules, mediastinal or hilar lymphadenopathy (40%), and effusion (40%) were the most common radiographic findings. The mean interval from initial diagnosis to diagnosis of EBM was 32.8 months (range, 0-96 months) and median survival time was 18 months (range, 4-84). As a conclusion, various extrapulmonary tumors can metastasize to the bronchus. Symptoms and radiographic findings are similar with those in primary lung cancer. Therefore, EBM should be discriminated from primary lung cancer histopathologically. Although mean survival time is usually short, long-term survivors were reported. Consequently, treatment must be planned according to the histology of the primary tumor, evidence of metastasis to other sites and medical status of the patient.

Pulmonary adenocarcinoma complicated with a pulmonary infarction presenting as an intrapulmonary metastasis is relatively rare. We present a case of pulmonary infarction manifesting as intrapulmonary metastases of lung cancer. A previously healthy 59-year-old woman was admitted to our hospital for evaluation of abnormal shadows in the right lower lung field. Laboratory tests showed no abnormalities except for a slight elevation of carcinoembryonic antigens (CEAs). Computed tomography (CT) of the chest revealed a hilar mass lesion with parenchymal lesions in the periphery of the right lower lobe, highly suspected to be a pulmonary adenocarcinoma with intrapulmonary metastases. A diagnosis of pulmonary adenocarcinoma was confirmed by a transbronchial brushing examination. A right middle and lower bilobectomy with mediastinal lymph node dissection was due to hilar lymphadenopathy and a lower lobe invasion of the main tumor. Histopathological findings of the resected specimens revealed poorly differentiated adenocarcinoma of the lung with N1 (number 11i and 12 l) disease and multiple pulmonary infarctions with coagulation necrosis and recanalization. Our case suggests that pulmonary infarction associated with lung cancer should be considered as one important cause of peripheral pulmonary nodules.
