1/369. Pseudomonal pericarditis complicating cystic fibrosis.patients with advanced cystic fibrosis typically have chronic bacterial infection of the upper and lower respiratory tracts, but rarely develop extrapulmonary sites of infection. We report a case of purulent pericarditis due to pseudomonas aeruginosa in a patient with cystic fibrosis and no other risk factors for pericarditis. This is a previously unreported complication in cystic fibrosis prior to lung transplantation.- - - - - - - - - - ranking = 1keywords = lung (Clic here for more details about this article) |
2/369. Multifocal osteosarcoma: an unusual presentation.PURPOSE: Report the unusual presentation, clinical course, and cytogenetic abnormalities in a child with multifocal osteosarcoma. patients AND methods: A 10-year-old boy had multifocal osteosarcoma involving the entire skeleton, pleura, bone marrow, and lungs. He had marked anemia, thrombocytopenia, and severe hypocalcemia at diagnosis. RESULTS: Despite aggressive chemotherapy, he died from progressive disease 1 month after diagnosis. cytogenetic analysis of tumor cells within the pleural fluid showed multiple chromosomal abnormalities with amplification of the c-myc oncogene. CONCLUSION: Multifocal osteosarcoma should be considered in the differential diagnosis of a child with pancytopenia and multiple bone lesions. Amplification of the c-myc oncogene may have had a significant role in the pathogenesis, etiology, and rapid progression of this patient's multifocal disease. Additional studies will be needed to determine the biologic significance of c-myc amplification in multifocal osteosarcoma.- - - - - - - - - - ranking = 1keywords = lung (Clic here for more details about this article) |
3/369. Digital clubbing in a patient with progressive mantle cell lymphoma.Digital clubbing with or without hypertrophic osteoarthropathy may occur in a variety of neoplastic diseases. We present the first description of digital clubbing in a patient with progressive mantle cell lymphoma, in the absence of any other apparent etiology. We suggest that clubbing might be a paraneoplastic manifestation in mantle cell lymphoma. The literature on digital clubbing in hematological neoplasms is reviewed.- - - - - - - - - - ranking = 0.46256554268031keywords = neoplasm (Clic here for more details about this article) |
4/369. Fatal invasive aspergillosis in an adolescent with cystic fibrosis.We report on a 13-year-old girl with cystic fibrosis (CF) who developed refractory airflow obstruction despite high-dose steroids. She developed invasive aspergillosis and died despite oral and intravenous antifungal therapy. We speculate that the increasing use of immunosuppressive strategies and aggressive antipseudomonal therapy in CF may lead to an increase in aspergillus lung disease, including invasive aspergillosis in the future.- - - - - - - - - - ranking = 1keywords = lung (Clic here for more details about this article) |
5/369. A retired shipyard worker with rapidly progressive pulmonary interstitial fibrosis.We present a case of progressive interstitial fibrosis in a retired shipyard worker who was exposed to asbestos during the postwar era of the late 1940s and 1950s, when asbestos exposures in the workplace were not regulated. Forty years later, at 63 years of age, the patient presented with restrictive lung disease. The patient was diagnosed with asbestos-related pleural disease and parenchymal asbestosis. He remained stable for the next 7 years, but then he began to manifest rapid clinical progression, which raised the possibility of an unusual variant of asbestosis, a concomitant interstitial process, or an unrelated disease. Lung biopsy was not undertaken because of the patient's low pulmonary reserve and limited treatment options. An empiric trial of oral steroids was initiated, but his pulmonary status continued to deteriorate and he died of pulmonary failure at 72 years of age. Many diseases result in pulmonary interstitial fibrosis. Ideally, open lung biopsy should be performed, but this procedure inevitably causes complications in many patients with end-stage restrictive lung disease. Furthermore, while the presence of asbestos bodies in tissue sections is a sensitive and specific marker of asbestos exposure, neither this finding nor any other charge is a marker indicative of asbestosis or the severity of asbestosis. With the enactment of the Asbestos Standard in the united states, asbestos exposures have been decreasing in this country. However, industries that produce asbestos products and wastes continue to expand in developing countries. Prevention of asbestos-related lung disease should be a global endeavor, and asbestos exposures should be regulated in both developed and developing countries.- - - - - - - - - - ranking = 4keywords = lung (Clic here for more details about this article) |
6/369. A man with a prosthetic ear and multiple pulmonary nodules.Basal cell carcinoma is generally regarded as a relatively indolent tumor easily controlled with local therapy. When neglected or inadequately treated this tumor can become locally aggressive and in rare circumstances metastasize. This report documents a case of basal cell carcinoma metastatic to the lung that resulted in rapidly progressive respiratory failure and death.- - - - - - - - - - ranking = 1keywords = lung (Clic here for more details about this article) |
7/369. An ACTH-producing pituitary carcinoma developing Cushing's disease.An autopsy case of an ACTH-producing pituitary carcinoma in a 59-year-old man who developed Cushing's disease is reported. The surgically removed pituitary tumor was diagnosed as chromophobe adenoma, however, pulmonary metastases appeared 2 years after the operation. autopsy revealed a residual pituitary tumor in the sella turcica with systemic metastases to the lungs, liver, pulmonary lymph nodes, hypothalamus, dura mater, and the subarachnoid space of the midbrain and spinal cord. immunohistochemistry revealed ACTH positivity in the tumor cells. Further immunohistochemical study showed positive high expression of Ki-67 in the tumor removed at surgery as well as in the autopsied tumor. Ki-67 labeling index provided valuable information about the invasive and proliferative potential compared to noninvasive benign pituitary adenoma.- - - - - - - - - - ranking = 1keywords = lung (Clic here for more details about this article) |
8/369. Rapid progression to high-grade dysplasia in Barrett's esophagus after liver transplantation.There is an increased incidence of malignancies in transplant recipients. Accelerated progression from a premalignant lesion to carcinoma has been reported in transplant recipients with skin cancer and colon cancer. Whereas Barrett's esophagus is a common premalignant condition in the normal population, rapid progression to severe dysplasia or carcinoma has not been widely reported in transplant recipients. We report on a liver transplant recipient who developed rapid progression from Barrett's esophagus without dysplasia to high-grade dysplasia within 9 months after transplantation.- - - - - - - - - - ranking = 8.5581922243706keywords = cancer (Clic here for more details about this article) |
9/369. Progressive pulmonary vascular disease after pulmonary artery banding and total correction in a case of ventricular septal defect and pulmonary hypertension.A 7-month-old infant with ventricular septal defect and pulmonary hypertension underwent pulmonary artery banding, which resulted in a decrease in the pulmonary arterial peak pressure from 102 to 54 mmHg. Lung biopsy findings showed at most an early grade 3 Heath-Edwards classification, and an index of pulmonary vascular disease of 1.4, both of which indicated operability for total correction. Small pulmonary arteries less than 100 microns in diameter, however, showed marked hydropic changes in the medial smooth muscle cells. Total correction was performed at the age of 2 years, but the pulmonary arterial pressure failed to decrease. A lung biopsy taken just after the closure of the ventricular septal defect contraindicated operability due to progressive pulmonary vascular disease at a grade 6 Heath-Edwards classification and an index of pulmonary vascular disease of 2.4. The patient died at 8 months after the operation, and an autopsy revealed still more advanced pulmonary vascular disease at a grade 6 Heath-Edwards classification and an index of pulmonary vascular disease of 2.8. The pathogenesis of arterial changes is discussed.- - - - - - - - - - ranking = 1keywords = lung (Clic here for more details about this article) |
10/369. Congenital hemihypertrophy and epithelioid haemangioendothelioma in a 10-year-old boy: a case report.Epithelioid haemangioendothelioma has not been previously described in a patient with congenital hemihypertrophy and diabetes mellitus. Hepatic nodules were incidentally discovered on a routine US examination searching for known associated abnormalities. Pulmonary nodules were present on chest X-ray and CT of the lungs. The diagnosis was confirmed by open biopsy of a hepatic nodule. Despite significant disease progression the patient remains symptom free.- - - - - - - - - - ranking = 1keywords = lung (Clic here for more details about this article) |
