BACKGROUND: Malignant pleural effusion in association with mesothelioma, bronchogenic carcinoma and breast carcinoma is common, although less frequently reported with other malignancies. We report a follicular variant of papillary thyroid carcinoma (FVPTC), diagnosed on fine needle aspiration cytology (FNAC) of thyroid and lymph nodes and subsequently proved to have metastasized to the pleural cavity. CASE: A 46-year-old man presented with history of breathlessness, thyroid swelling, pleural effusion and bilateral cervical lymphadenopathy. FNAC of the thyroid swelling and the lymph nodes showed features of FVPTC with cervical lymph node metastasis. Pleural fluid examination led to suspicion of pleural involvement by metastatic deposit, confirmed by subsequent pleural biopsy. CONCLUSION: Thyroid malignancies presenting with pleural effusion are rare. In this case, although pleural fluid cytology suggested involvement of pleura, a definitive diagnosis could be rendered only on pleural biopsy. An ancillary aid, such as immunocytochemistry, could have helped establish pleural involvement on routine pleural fluid cytology alone. This case emphasizes the possible existence of rare cases of FVPTC that may be associated with a dismal prognosis. In our case, initial diagnosis of FVPTC could be made only on correlating FNA features of thyroid aspirate with those of lymph node aspirate. 相似文献

Review of the records of 243 cases of cytologically diagnosed non-Hodgkin's lymphomas (NHL) revealed pleural effusions in 21 (8.6%). Cytologic examination of pleural fluid was done in 17 cases, of which 16 were reported as positive. Cytologic examination was supplemented with cytochemical staining (acid phosphatase, alpha naphthyl acetate esterase and periodic-acid-Schiff reactions) and E-rosetting studies in 12 cases. Of the 16 positive cases, 11 were malignant lymphomas consisting of convoluted lymphocytes. Acute lymphatic leukemia of the prothymocytic type (T-ALL) and chronic lymphocytic leukemia of the T-cell type (T-CLL) comprised one case each, and there were three cases of follicular center cell lymphomas, two of the cleaved-cell type and one of the Burkitt-type. Comparison of the cytomorphology of the tumor cells in the pleural effusion with those in fine needle aspiration smears from the solid tumors in 14 cases showed an identical appearance in 13 cases; in one, the Burkitt-type lymphoma, the cells were larger and more pleomorphic in the pleural effusion. This study indicates that the cytologic diagnosis and categorization of NHL of the convoluted-cell type is greatly enhanced by the study of neoplastic lymphocytes in a pleural effusion. 相似文献

BACKGROUND: Systemic anaplastic large cell lymphoma (ALCL) is predominantly a nodal disease, but extranodal involvement can occur during the disease course or as the primary presentation. We report two rare cases of ALCL presenting with a pleural effusion, mimicking primary effusion lymphoma (PEL). CASES: Two patients, a 47-year-old woman and an 81-year-old man, presented with a pleural effusion for investigation. The pleural fluid contained abundant, large, lymphoid cells with marked nuclear atypia. These neoplastic cells strongly expressed CD30 and EMA and showed a T-cell phenotype (CD3+CD45RO+ for case 1 and CD4+ for case 2). Case 1, in addition, showed ALK1 expression. The tumor cells in both cases were negative for human herpes virus type 8 (HHV8) and Epstein-Barr virus (EBV). ALCL shows overlapping cytologic features with PEL, but the T-cell phenotype, ALK1 expression in case 1, lack of association with HHV8 and EBV, HIV seronegativity and subsequent discovery of nodal disease in case 2 were all in favor of ALCL over PEL. CONCLUSION: In rare cases a pleural effusion is the presenting feature of ALCL, and distinction from PEL depends on correlation with clinical findings, detailed immunophenotyping and study of the status of HHV8 and EBV. 相似文献

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. 相似文献

Three patients with pleural effusion were found to have pancreaticopleural fistulas passing through an opening in the diaphragm are reported. In one case the effusion was purulent and originated from an abscess of the pancreas. Retrograde pancreatography during operation defined the course of the fistula. In two other cases the fistula was demonstrated by radiography after intrapleural injection of contrast medium. The diagnostic importance of injecting contrast medium early into the pleural cavity in cases of effusion rich in amylase, before lung expansion obscures the fistula, is emphasized. Cases of pancreaticopleural fistula may be commoner than supposed. 相似文献

Pleural effusion cytology in a case of cytophagic histiocytic panniculitis (subcutaneous panniculitic T-cell lymphoma). A case report 总被引:2,自引:0,他引:2
BACKGROUND: Cytophagic histiocytic panniculitis (CHP) presents with subcutaneous panniculitis associated with hemophagocytic syndrome. Many cases of CHP are now being classified as a natural disease progression of subcutaneous panniculitic T-cell lymphoma (SPTL). There have been no cytologic reports dealing with pleural aspirates in cases of CHP or SPTL. CASE: A pleural aspirate obtained from a 19-year-old female revealed lymphoma cells and hemophagocytic histiocytes. A skin biopsy specimen showed the presence of CD8-positive lymphoma cells in fat lobules associated with cytologically benign histiocytes with erythrophagocytosis and lymphophagocytosis. CONCLUSION: Hemophagocytic histiocytes were seen in the pleural effusion from a patient with SPTL. 相似文献

We performed an investigation focusing on the distribution of tumor types responsible for positive pleural effusions in 143 patients who died of malignancy and underwent autopsy. The principal malignant tumors were lung carcinoma (41 cases, 51.2%) and pleural mesothelioma (23 cases, 28.7%) in males and breast carcinoma (24 cases, 38.2%) and lung carcinoma (13 cases, 20.6%) in females. Histologically, most of the cases belonged to the adenocarcinoma category. The first morphologic diagnosis was a cytologic one in 86 cases (60.1%), especially regarding lung cancer. In breast cancer a positive pleural effusion always preceded recurrent disease with a rapidly progressive course, even a long time after the initial surgery. The results of this study, based on both cytomorphologic features and postmortem data on the tumor sites, may be a useful working framework for the cytologist dealing with a positive pleural effusion. 相似文献

Introduction
Polycystic liver disease is asymptomatic in 95% of patients. In the remaining 5% it causes symptoms due to the local mass effect of the polycystic liver. We describe the case of a patient who presented with symptoms of a pleural effusion and was also found to have polycystic liver disease. The effusion recurred despite repeated efforts at drainage and only resolved following surgical debridement of the cystic liver.Case presentation
A 50-year-old Caucasian woman presented with a two-week history of increasing dyspnoea. An examination revealed a large right pleural effusion and gross hepatomegaly. An ultrasound confirmed a large polycystic liver and diagnostic thoracocentesis revealed an exudate, which was sterile to culture. The pleural effusion proved refractory to drainage and our patient underwent surgery to deroof the main hepatic cysts in an attempt to reduce the pressure on her right diaphragm. The histology was compatible with that of polycystic liver disease. No evidence of malignancy was found. After surgery, our patient had no recurrence of her effusion and, to date, has remained asymptomatic from her polycystic liver disease.Conclusion
The case in this report illustrates that an exudative pleural effusion is a rare complication of polycystic liver disease. We feel that the mechanical effects of a large polycystic liver, and subsequent disruption of sub-diaphragmatic capillaries, resulted in a persistent exudative pleural effusion. Thus, surgical debulking of the hepatic cysts is required to manage these effusions. 相似文献13.

Pleural effusion, an accumulation of pleural fluid, contains proteins originating from plasma filtrate and, especially when tissues are damaged, parenchymal interstitial spaces of lungs and/or other organs. This report presents data of the first global proteomic analysis of human pleural effusion. A composite sample was prepared by pooling pleural effusions from seven lung adenocarcinoma patients. Two-dimensional gel electrophoresis analysis of the composite sample revealed 472 silver-stained spots. 242 selected gel spots were subjected to protein identification by in-gel digestion, liquid chromatography-tandem mass spectrometry, and sequence database search. 44 proteins were identified with higher confidence levels (at least two unique peptide sequences matched), while 161 other proteins were identified at the minimal confidence level (only one unique peptide sequence matched). The data provide fundamental information on the composition of protein contents in human pleural effusion. Among these 44 proteins that were identified with higher confidence levels, 7 proteins, retinoblastoma binding protein 7, synaptic vesicle membrane protein, corticosteroid binding globulin precursor, PR-domain containing protein 11, envelope glycoprotein, MSIP043 protein, and titin have not been reported in plasma and may represent proteins specifically present in pleural effusion. These proteins could have originated from parenchymal interstitial spaces and represent potential candidates of useful biomarkers that could not be readily detected in plasma but in pleural effusion. Retinoblastoma binding protein 7 is of special interest since it may play a role in the regulation of cell proliferation and differentiation. 相似文献

BACKGROUND: Extraneural metastasis of oligodendroglioma is extremely rare and is diagnosed primarily by biopsy or autopsy and very occasionally by fine needle cytologic examination. We report a case of metastatic oligodendroglioma diagnosed by cytologic examination of a pleural effusion. Such a diagnosis has not been reported before. CASE: A 64-year-old woman developed anemia and bilateral pleural effusion 7 years after an operation for an oligodendroglioma over the left frontal lobe. Cytologic examination of the pleural effusion showed aggregates of atypical polygonal cells containing round, hyperchromatic nuclei and scanty, granular cytoplasm in Liu's and Papanicolaou stain and cell blocks. Immunohistochemical staining of the tumor cells revealed a positive reaction for antibodies to glial fibrillary acidic protein, S-100 and Olig2. Pleural biopsy confirmed the cytologic diagnosis of pleural effusion. A pathologic fracture of the right humeral and femoral bones was noted 1 month later, and the specimen also showed infiltrating oligodendroglioma cells in bone tissue. CONCLUSION: To the best of our knowledge, this is the first metastatic oligodendroglioma diagnosed by pleural cytology. Fine needle cytology can provide a reliable and rapid way to detect an extracranial metastatic oligodendroglioma in different organs. 相似文献
