1/39. Management of pleural effusions in children with malignant lymphoma.PURPOSE: The aim of this study was to determine potential problems in the diagnosis and management of children with pleural effusions and malignant lymphoma as well as the efficacy of thoracentesis. methods: The case histories of six children with malignant lymphoma who presented with pleural effusions were reviewed. Thoracentesis was performed using the Seldinger technique. RESULTS: Four of the children presented with symptoms and chest radiograph findings similar to pneumonia. A large mediastinal mass was present in two children. Pleural fluid analysis resulted in a definitive diagnosis of lymphoma in five of the six children. Two of the children had symptoms of reexpansion pulmonary edema after removal of pleural fluid. An empyema developed in one child after thoracotomy and chest tube placement. Reaccumulation of pleural fluid was common before initiating chemotherapy. CONCLUSIONS: Malignant pleural effusions frequently are present in children with non-Hodgkin's lymphoma. They may present with respiratory distress because of the size of the effusion, the mediastinal mass, or both. Management of these pleural effusions is associated with potential complications, some of which are life threatening. Thoracentesis is the initial diagnostic and therapeutic procedure of choice. The use of a Seldinger technique for thoracentesis has proved useful and safe. In patients with large effusions, aggressive removal of the pleural fluid may be followed by reexpansion pulmonary edema.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
2/39. rhabdomyosarcoma in a child with massive pleural effusion: cytological diagnosis from pleural fluid.We report on a case of embryonal rhabdomyosarcoma in an 11-yr-old boy investigated for mild chest pain after trauma. Chest radiography showed a massive right pleural effusion. Cytological analysis of the pleural fluid demonstrated the presence of malignant small undifferentiated cells. The rhabdomyoblastic nature of the cells was confirmed by positive immunostains of HHf35 actin, desmin, and skeletal muscle myosin; histological examination of a core biopsy confirmed the diagnosis of rhabdomyosarcoma. Computed tomography and gallium scan revealed the presence of an extensive anterior and lower chest wall mass involving the mediastinum, as well as retroperitoneal lymphadenopathy. Massive pleural effusion is a frequent presentation in malignant disease, but is rare in rhabdomyosarcoma. The immunochemical stain studies performed on cytological smears in this case proved to be very useful for making the definitive and accurate diagnosis. Diagn.

3/39. Low-grade B-cell lymphoma of mucosa-associated lymphoid tissue in the lung: a report of a case with pleural dissemination.A 79-year-old man with an abnormal shadow on a chest radiograph was referred to our hospital for further examination. Open lung biopsy revealed numerous nodules on visceral pleura and the tumor, obtained by wedge resection of the left upper lobe of the lung, consisted of centrocyte-like cells and lymphoplasmacytoid cells, expressing CD20 and CD79a. These cells invaded bronchiolar epithelium to form lymphoepithelial lesions. The pleural-based nodules were similarly composed of the same cells as those in the left upper lobe tumor. To our knowledge, pleural dissemination of low grade B-cell lymphoma of mucosa-associated lymphoid tissue has not been reported previously.- - - - - - - - - - ranking = 0.5keywords = chest (Clic here for more details about this article) |
4/39. Subcutaneous seeding after ultrasound-guided placement of intrapleural catheter. An unusual complication of the intracavitary palliative treatment of pleural mesothelioma.Intrapleural catheters are useful in the palliative treatment of malignant effusions. Complications are infrequent and of little importance. We report a case of subcutaneous implantation metastasis along the course of intrapleural catheter, which had been placed under sonographic guidance in a patient with pleural mesothelioma. After drainage of the effusion, cisplatin plus cytarabine was administered via the chest tube, achieving complete remission of the pleural effusion. Subcutaneous metastasis became evident 3 months later and was the only sign of disease progression for 2 months. The seeding of cancer cells was probably caused by a small leakage of fluid around the chest tube that occurred during the placement procedure as a result of the increased intrapleural pressure caused by the large quantity of fluid that had accumulated in the pleural space.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
5/39. Tension pneumoperitoneum associated with a pleural-peritoneal shunt.The differential diagnosis of pneumoperitoneum is broad. We report a case of tension pneumoperitoneum in a patient on mechanical ventilation with initially unrecognized pneumothorax who had an indwelling pleural-peritoneal shunt. The patient developed ventilatory and hemodynamic collapse as air was diverted from the pleural space into the peritoneal cavity. Subsequent abdominal exploration revealed the source of the intra-abdominal air. Placement of a chest thoracostomy tube and removal of the pleural-peritoneal catheter resulted in significant clinical improvement. We suggest that it is important to recognize that pleural-peritoneal catheters may cause tension pneumoperitoneum without obvious concurrent pneumothorax.- - - - - - - - - - ranking = 0.5keywords = chest (Clic here for more details about this article) |
6/39. Disseminated lymphangiomatosis presenting with massive chylothorax.BACKGROUND: Lymphangiomatosis is a disease characterized by involvement of various body constituents and can involve the skeletal system, connective tissues, and visceral organs. MATERIALS AND methods: We present a case of a 9-year-old girl where this entity presented with extensive right-sided chylothorax. Conventional imaging, including skeletal scintigraphy and contrast enhanced CT of the chest and abdomen, may have underestimated the extent of the disease, as seen on follow-up T2-weighted MR images of the chest and abdomen in our case. RESULTS: MRI easily demonstrated additional bone lesions as well as multiple small splenic lesions, which were difficult to appreciate on prior CT examinations. CONCLUSION: We suggest that MRI may be helpful to assess the extent of this disease more accurately.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
7/39. Ruptured giant intrathoracic lipoblastoma in a 4-month-old infant: CT and MR findings.BACKGROUND: We describe a 4-month-old infant with a ruptured intrathoracic lipoblastoma arising from the parietal pleura and associated with a pleural effusion. OBJECTIVE: The clinical presentation was rapidly evolving respiratory distress. The chest radiograph showed a large mass and a pleural effusion in the right thoracic cavity. CT demonstrated an inhomogeneous low-attenuation mass which was 7 cm in diameter and which showed areas of enhancement after intravenous contrast medium. MRI showed a fatty intrathoracic mass with intratumoral streaks and whorls, which were attributed to loose fibrovascular connective tissue on pathological examination. RESULTS: thoracotomy and pathological examination revealed a ruptured intrathoracic lipoblastoma arising from the parietal pleura. CONCLUSION: The pleural effusion might have suggested rupture of the tumour.- - - - - - - - - - ranking = 0.5keywords = chest (Clic here for more details about this article) |
8/39. Extrapleural pneumonectomy for sarcomas report of two cases.AIMS AND BACKGROUND: Extrapleural pneumonectomy (EPP), which is a very uncommon surgical procedure, is electively indicated only in patients with early stages of malignant pleural mesothelioma, a rare condition. Two adults suffering from sarcomas and treated with EPP are described here. methods: A 29-year-old male with four left-sided lung metastases and ipsilateral pleural effusion from a chondrosarcoma of the mandibula and a 64-year old woman with a megamass in the left chest due to a local recurrence of a hemangiopericytoma underwent EPP. RESULTS: Extra-EPP-field multiorgan progression was diagnosed 14 months following surgery in the first patient who died at the 24th postoperative month but remained free of disease at the site of surgery. The second patient had a chest wall relapse at the forty-third month following EPP, which was treated by partial resection of the second and third ribs. She is alive and disease-free at the twelfth postoperative month. DISCUSSION: EPP may be considered for salvage treatment in selected patients with intrathoracic sarcomas not amenable to other effective therapies to achieve mid- to long-term disease control, even in the case of advanced spread.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
9/39. Pleuroperitoneal shunts and tumor seeding.A 76-year-old man with malignant mesothelioma of the left pleura was referred for surgical palliation. He was dyspneic at rest and had anterior chest pain and a persistent cough. Chest x-ray film revealed an extensive left pleural effusion. A thoracoscopy was performed, and 3L of pleural fluid was drained. Both the pleural surfaces and rhe diaphragm were studded with tumors. On maximal inflation of the lung, the parietal and visceral pleura did not oppose, and therefore a Denver shunt was inserted. At 6 weeks follow-up, the shunt was performing satisfactorily. At follow-up 9 weeks postoperatively, the subcutaneous tunnel was infiltrated by mesothelioma over a distance of some 15 cm.- - - - - - - - - - ranking = 1.5550852551301keywords = chest pain, chest (Clic here for more details about this article) |
10/39. Primary effusion lymphoma (PEL) in hiv-negative patients--a distinct clinical entity.Primary effusion lymphoma (PEL) is a recently described rare type of non-Hodgkin's lymphoma occurring almost exclusively in hiv infected people. Human herpesvirus 8 (HHV-8), has been linked with PEL, and a causative relationship has been suggested. In the vast majority of PEL cases Epstein-Barr virus (EBV) has been found in the tumour cells. We describe here an elderly human immune deficiency (hiv) seronegative man with intractable chest pain and pleural effusion. The diagnosis of malignant lymphoma was suggested cytologically and confirmed histologically following pleural biopsy. No lymphadenopathy or organ involvement with lymphoma was found. Systemic chemotherapy with a modified CHOP regimen with G-CSF support gradually led to the resolution of the chest pain and ultimately resulted in a complete clinical remission (CCR). The presence of HHV-8 was demonstrated by PCR using paraffin-embedded tissue samples from the involved pleura, whereas EBV-associated genetic material was absent. The patient remained in CCR for 18 months and died of an unrelated cause (cerebrovascular event). Only 11 other cases with clinical and virological features similar to those of our patient have been reported in the literature. Analysis of these rare cases suggests hiv-negative EBV-negative PEL to be a distinct clinical entity with epidemiological features resembling classical KS and supports an EBV-independent role for HHV-8 in the pathogenesis of PEL.- - - - - - - - - - ranking = 3.1101705102602keywords = chest pain, chest (Clic here for more details about this article) |
