1/86. Posttransplantation lymphoproliferative disorder mimicking a nonspecific lymphocytic pleural effusion in a bone marrow transplant recipient. A case report.BACKGROUND: Serous effusions are rare complications of bone marrow transplantation (BMT) and result mainly from infections or tumor relapse. CASE: We report a case of posttransplantation lympho-proliferative disorder (PTLD) revealed by cytodiagnostic examination of serous effusions in a BMT recipient. The effusion was initially considered reactive, but morphologic, immunocytologic and molecular studies subsequently revealed PTLD. CONCLUSION: This case demonstrates the importance of cytologic examination of effusions in BMT or organ recipients. Since most PTLDs are Epstein-Barr virus (EBV)-associated B-cell lymphoproliferative disorders and T cells predominate in reactive effusions, appropriate initial immunostaining, including CD3, CD79a and EBV latent membrane protein, should aid in their early detection.- - - - - - - - - - ranking = 1keywords = life (Clic here for more details about this article) |
2/86. Non-surgical treatment of purulent pericarditis, due to non-encapsulated haemophilus influenzae, in an immunocompromised patient.A 59-year-old woman suffering from rheumatoid arthritis was admitted with pleural empyema and pericarditis due to non-encapsulated H. influenzae, and developed signs of cardiac tamponade. Purulent pericarditis resolved after ultrasound-guided percutaneous aspiration and systemic antimicrobial therapy. Serial echocardiographic examinations showed a slowly vanishing effusion. Long term follow-up revealed no evidence of pericardial constriction. This case illustrates that life-threatening purulent pericarditis in an immunocompromised patient may respond well to non-surgical treatment.- - - - - - - - - - ranking = 0.16666666666667keywords = life (Clic here for more details about this article) |
3/86. Massive pleural effusions in cryptococcal meningitis.Cryptococcal infection uncommonly presents with pulmonary manifestations and even more rarely so as massive bilateral effusions. Pleural involvement is usually associated with underlying pulmonary parenchymal lesions and is unusual while on antifungal therapy. We report a patient with cryptococcal meningitis who, while on intravenous 5-flucytosine and amphotericin b, developed life-threatening bilateral massive pleural effusions with evidence of spontaneous resolution, consistent with prior hypothesis of antigenic stimulation as the cause of pleural involvement.- - - - - - - - - - ranking = 0.16666666666667keywords = life (Clic here for more details about this article) |
4/86. Glycinothorax: a new complication of transurethral surgery.A 76-year-old woman sustained inadvertent perforation of her posterior bladder wall during transurethral resection of a bladder tumour. In the immediate postoperative period, she developed life-threatening respiratory failure following the formation of a large, unilateral pleural effusion. After therapeutic drainage, biochemical analysis of the effusion revealed that it had a high concentration of glycine. The fluid used for intra- and postoperative bladder irrigation had leaked from the perforated bladder and collected in the pleural cavity. This type of hydrothorax complicating endoscopic urological surgery has not been described previously.- - - - - - - - - - ranking = 0.16666666666667keywords = life (Clic here for more details about this article) |
5/86. Unilateral pleural effusion complicating central venous catheterisation.Acute respiratory distress developed in two preterm babies because of unilateral hydrothorax secondary to the migration of a central venous catheter into the pulmonary vasculature. Prompt recognition of the problem and rapid treatment are essential and life saving. This complication of intravenous alimentation catheters has not been previously reported in the neonatal age group.- - - - - - - - - - ranking = 0.16666666666667keywords = life (Clic here for more details about this article) |
6/86. association of a chromosomal abnormality with lymphocytes having both T and B markers in a patient with lymphoproliferative disease.The lymphocytes of a patient with leukemic lymphosarcoma were found to have an unusual surface phenotype in that they bound both sheep erythrocytes (a T cell marker) and complement-coated erythrocytes (a B cell marker) but lacked other B cell surface characteristics. Marker chromosomes were present in these cells, but not in other, phenotypically normal cells from the same patient. This case may provide a clue to the chromosomal origin of some lymphocyte surface markers in man.- - - - - - - - - - ranking = 0.66666666666667keywords = life (Clic here for more details about this article) |
7/86. waldenstrom macroglobulinemia presenting as a pleural effusion.We describe a patient with waldenstrom macroglobulinemia who presented with a lymphocytic pleural effusion. Pleural involvement in waldenstrom macroglobulinemia is very rare. In addition, to our knowledge, there are no reports in the literature in which a primary diagnosis was made on the basis of pleural fluid analysis. The presence of small lymphocytes in serous cavity fluid can pose great difficulty in the differentiation between a low-grade lymphoproliferative disorder and reactive lymphocytosis. The diagnosis of malignancy in this case was established on the basis of morphologic testing, flow cytometry, and the detection of B-cell immunoglobulin gene rearrangement.- - - - - - - - - - ranking = 0.16666666666667keywords = life (Clic here for more details about this article) |
8/86. An uncommon etiology of isolated pleural effusion. The ovarian hyperstimulation syndrome.We report three cases of pleural effusion in the context of ovarian stimulation for in vitro fertilization. The ovarian hyperstimulation syndrome usually causes pleural effusion and ascites. When the latter is lacking, an isolated pleural effusion in a pregnant patient can be mistaken for pulmonary embolism. Early recognition of the condition should allow for an appropriate diagnostic and therapeutic management. Except for some rare but life-threatening complications, such as major hypovolemia or respiratory distress syndrome, the spontaneous outcome is usually favorable. The pathogenesis of this condition may involve an increase of capillary permeability due to the release of vasoactive mediators.- - - - - - - - - - ranking = 0.16666666666667keywords = life (Clic here for more details about this article) |
9/86. Cytologic finding of chyloascites in lymphangioleiomyomatosis. A case report.BACKGROUND: lymphangioleiomyomatosis is a rare disease, histologically characterized by an abnormal proliferation of smooth muscle around the lymphatics. lung is the most common site of involvement, and patients usually present with dyspnea, chest pain, and cough. Chylous pleural effusion and ascites occasionally appear during the course of the disease. There are only a few reports on the cytologic findings in this disease. To our knowledge, the cytologic findings of chylous pleural effusion and chyloascites have not been reported before. CASE: A 23-year-old female presented with chylothorax, chyloascites and a retroperitoneal mass. Cytologic examination of chylous pleural effusion and chyloascites revealed numerous cohesive and thick clusters of cells with a high nuclear/cytoplasmic ratio, oval nuclei and slightly increased chromatin content. mitosis and necrosis were not observed. Exploratory laparotomy and transbronchial lung biopsy were performed, and the histologic diagnosis was lymphangioleiomyomatosis involving the retroperitoneal lymph nodes, uterine fundus and lungs. immunohistochemistry showed that the characteristic clusters in chylous fluids were positive for alpha-smooth muscle actin. CONCLUSION: A diagnosis of lymphangioleiomyomatosis is possible from cytologic findings of effusions with the aid of clinical findings.- - - - - - - - - - ranking = 0.16666666666667keywords = life (Clic here for more details about this article) |
10/86. Pleural posttransplantation lymphoproliferative disorder following liver transplantation.A case of posttransplantation lymphoproliferative disorder (PTLD) involving the pleura is reported. The patient was a 57-year-old man who underwent liver transplantation 2 years prior to the development of PTLD. The PTLD was pleural-based and was first detected by radiologic studies as a pleural effusion. Transbronchial biopsy and cytologic examination of 2 pleural fluid specimens were nondiagnostic. Subsequent open-wedge biopsy revealed a monomorphic PTLD, composed of large immunoblasts with plasmacytoid differentiation. Immunohistochemical studies demonstrated B-cell lineage with expression of monotypic cytoplasmic immunoglobulin kappa light chain and CD79a, and absence of T-cell antigens. Immunohistochemical and in situ hybridization studies demonstrated Epstein-Barr virus protein and rna, respectively. No evidence of human herpesvirus 8 dna was detected by polymerase chain reaction. We report this case because pleural-based PTLD is rare. The diagnosis of this entity is made more difficult by the fact that PTLD is often underrepresented in pleural fluid cytology samples.- - - - - - - - - - ranking = 0.83333333333333keywords = life (Clic here for more details about this article) |
