Abstract
Pleuropulmonary blastoma is a rare and aggressive primary intrathoracic neoplasm of children. T'he prognosis is extremely poor with frequent metastasis to the brain and bone. A 4-year-old boy successfully treated with multimodal therapy despite unfavorable prognostic factors is presented. The authors support the use of aggressive treatment of pleuropulmonary blastoma with surgery, chemotherapy, and radiotherapy.

Abstract
PURPOSE To determine the radiologic findings of pulmonary blastoma on chest radiograph and CT. MATERIALS AND METHODS Chest radiographs and CT scans of five patients with pathologically proven pulmonary blastoma were retrospectively evaluated and radiologic findings were correlated with histopathologic findings. RESULTS On chest radiograph, the pulmonary blastoma manifested as a solitary parenchymal mass (n = 2), a solitary parenchymal nodule (n = 1), hilar bulging with fingerlike parenchymal opacities (n = 1), or opacification of hemithorax (n = 1). On CT, the pulmonary blastoma manifested as a solitary parenchymal mass (n = 2), a solitary parenchymal nodule (n = 1), an endobronchial mass with postobstructive pneumonitis (n = 1), or a parenchymal mass with multiple subpleural masses and pleural effusion (n = 1). CONCLUSION Pulmonary blastomas most commonly manifested as a solitary parenchymal mass on chest radiograph and CT. These radiologic features are nonspecific and many primary or metastatic tumors of the lung could be included in differential diagnosis.

Abstract
Pleuropulmonary blastoma (PPB) is a rare malignant dysontogenetic neoplasm primarily affecting children and is characterized histologically by a variably mixed blastematous and sarcomatous patterns. We herein report a very exceptional adult case of PPB. A 21-yr-old male patient presented with a left chest pain of two weeks' duration. A computed tomography scan revealed a large, multicystic tumor occupying the left lower hemithorax, leading to the impression of a ruptured mediastinal cystic teratoma. A thoracotomy for resection of the tumor was performed. On histologic examination, the tumor consisted of cystic walls and associated solid lesions which showed undifferentiated blastemal tissues with focal fibrosarcomatous and rhabdoid features. Immunohistochemically the tumor cells only showed diffuse strong positivity for vimentin. The histologic findings corresponded to a type II PPB. The authors suggest that PPB, especially of type I or II, should be included in the radiologic differential diagnosis of mediastinal cystic neoplasms in a young adult.

Abstract
Pulmonary blastoma is a rare seen malignant tumor. It is generally reported in adults. The tumor including immature mesenchimal and/or epithelial structures is morphologically similar to fetal lung tissue. In this study, a male patient having been operated is presented because of the mass found in his chest X-ray. The lesion is histopathologically reported as a pleuropulmonary blastoma. The literature is reviewed because this case has a bad prognosis and is rarely seen.

Abstract
Pleuropulmonary blastoma (PPB) is a rare and aggressive malignant tumor of the lung. Approximately 80 cases of PPB have been published, and in only three cases high-dose chemotherapy with autologous hematopoietic stem cell transplantation (HSCT) was applied. A 5-year-old girl presenting with cough, fever, and shortness of breath was referred to the authors in March 1999. A computed tomography scan of the chest showed a tumor mass in the left hemithorax. The lesion was biopsied and the histopathologic report suggested the diagnosis of PPB. The patient received chemotherapy comprising vincristine, actinomycin D, and cyclophosphamide with only a minor response, and treatment was switched to ifosfamide, carboplatin, and etoposide, which produced a partial response. Tumor resection was performed, but margins were positive for PPB. Due to the high risk of recurrence, the authors elected to administrate high-dose chemotherapy using melphalan, etoposide, and carboplatin, followed by autologous HSCT. The patient achieved complete hematologic recovery, and reimaging after HSCT showed no evidence of disease. She relapsed 4 months later and died about 9 months after the completion of high-dose therapy. The role of high-dose chemotherapy and autologous HSCT is likely to be limited in PPB.

Abstract
OBJECTIVE Identification of clinical features suggestive of pulmonary blastoma (PB) through a retrospective comparison with cases of non-small cell lung cancer (NSCLC) operated during the same period. METHODS Between 1977 and 1999, five patients were operated for PB at Geneva University Hospital (four women and one man, aged 32-46 years--mean 36.8) versus 1913 consecutive patients (1558 men and 355 women, mean age 61.2) for primary NSCLC. In the PB subgroup (0.3%), the pulmonary tumor was single, located in an upper lobe in all but one instance, and measured between 5 and 13 cm (mean 9.6), whereas in the total NSCLC group, 27% of patients had tumors <3 cm (T1), evenly distributed in both lungs. All but one PB patients were symptomatic, compared to 45% in the NSCLC group. RESULTS The five patients with PB underwent curative pulmonary excisions (lobectomy in three and pneumonectomy in two) with mediastinal lymph node sampling. Pathological examination revealed extensive tumor necrosis in four, and N2 lymph node metastases in four (in the total NSCLC group, N2 disease was diagnosed in 21%). Postoperatively, three PB patients received radio- and/or chemotherapy. Four patients died between six and 30 months after the operation (mean 15), whereas 5-year survival in the NSCLC group was 32%, with a median survival of 3.7 years; the fifth patient is alive 28 months later, without any sign of recurrence. CONCLUSIONS Compared to operated NSCLC, PB are rare, large, and symptomatic tumors; they affect younger patients and carry a worse prognosis.

Abstract
Although most lesions that occur in the chest have a nonspecific soft-tissue appearance, fat-containing lesions are occasionally encountered at cross-sectional computed tomography (CT) or magnetic resonance imaging. The various fat-containing lesions of the chest include parenchymal and endobronchial lesions such as hamartoma, lipoid pneumonia, and lipoma. Endobronchial hamartoma usually appears at CT as a lesion with a smooth edge, focal collections of fat, or fat collections that alternate with foci of calcification. Mediastinal fat-containing lesions include germ cell neoplasms, thymolipomas, lipomas, and liposarcomas. The most frequent CT manifestation of the germ cell neoplasm teratoma is a heterogeneous mass with soft-tissue, fluid, fat, and calcium attenuation. Cardiac lesions with fat content include lipomatous hypertrophy of the interatrial septum and arrhythmogenic right ventricular dysplasia. Diagnosis of the former is made with CT when a smooth, nonenhancing, well-marginated fat-containing lesion is identified in the interatrial septum. Finally, fat may herniate into the chest at several characteristic locations. When such a lesion is identified, the time required for differential diagnosis is significantly reduced, often allowing a definitive radiologic diagnosis. Sagittal and coronal reformatted images can add valuable information by showing diaphragmatic defects and hernia contents.

Abstract
Pleuropulmonary blastoma is a rare intrathoracic neoplasm almost solely confined to childhood. Survival is poor. The authors report 2 children with extensive intrathoracic disease who are long term survivors after multimodal therapy. Both children received multiagent neoadjuvant chemotherapy, followed by surgical resection to remove all gross tumor. Postoperative chemotherapy was given to both children; radiotherapy was also given in the second case because of a question of positive tumor margins. Experience supports the use of multimodal therapy, including an aggressive surgical approach in the potentially curative treatment of this tumor.

Abstract
A three-and-half-year-old boy presented with recurrent chest infections, fever and weight loss of three month duration not responding to antibiotics. The chest X-ray and CT scan revealed a large well-circumscribed mass in right upper thorax with collapse of right upper lobe. A preoperative diagnosis could not be made even after fine needle aspiration cytology. Thoracotomy and right upper lobectomy was done and the biopsy report was an inflammatory pseudotumor. The child remained well for three months after which his symptoms and the mass recurred. The histopathology slides were reviewed and revealed a biphasic malignant tumor suggestive of Pulmonary Blastoma (PB). Patient received four cycles of chemotherapy followed by re-exploration. The recurrent tumour could only be excised partly and the child succumbed to persistent shock postoperatively. The final histopathological diagnosis was confirmed as PB. Primary pulmonary neoplasms in children are rare and of these PB which is even rarer, constitutes less than 15%. The report highlights that the lack of familiarity with this entity still causes error in the diagnosis of PB.

Abstract
A case of a 4-year-old girl with pleuropulmonary blastoma is reported. Surgical resection of the tumor was performed and histologic examination revealed pleuropulmonary blastoma with rhabdomyosarcomatous differentiation. Postoperative chemotherapy was administered and 3 weeks after initiation of treatment protocol a second site of lesion in the retroperitoneum was revealed with extension to the mediastinum, which shared similar mesenchymal neoplastic characteristics to the previously diagnosed primary lesion. The girl died 4 1/2 months after initial evidence of disease because of brain metastasis, indicating a very aggressive neoplasm unresponsive to treatment.

Abstract
Pulmonary blastoma is a rare non-small-cell lung cancer. In a statistically significant proportion of cases it is combined with cystic lung disease in children. The biphasic pulmonary blastoma and the well-differentiated fetal adenocarcinoma are the most frequent manifestations of pulmonary blastoma. If metastatic disease is ruled out, surgical therapy should be guided by the principles for radical therapy of NSCLC. There are no sufficient recommendations yet for therapy of stage IIIb and IV (UICC 1997) disease.

Abstract
Pulmonary blastoma (PB) is a rare malignant pulmonary tumor composed of immature mesenchyme and/or epithelium that resembles an embryonic lung at 10-16 weeks gestation. PBs constitute only 0.25 to 0.5 percent of all primary malignant lung tumors. Approximately 20 percent of the reported cases have occurred in pediatric patients. A seven-year-old girl presented with fever, cough, respiratory distress and chest pain on the left side. An x-ray, ultrasonography and a computed tomographic scan of the chest showed a large mass consisting of solid and cystic components almost completely occupying the left hemithorax associated with pleural effusion. The diagnosis of biphasic PB was established by histological examination of thoracotomy material. The patient was considered inoperable due to tumor involvement of the mediastinum, and she died two days after the initiation of chemotherapy. We report this case of PB to raise attention to the clinical, radiological and pathological features of PB in childhood because of its rarity.

Abstract
A five-month-old infant presented with a sudden choking cough and mild dyspnea. Bilateral cystic pulmonary images were found on a chest X-ray, leading to exploratory surgery. A pleuropulmonary blastoma, a rare malignant embryonic tumor of childhood, was diagnosed on histologic examination. This case illustrates the necessity of performing surgical resection and histologic evaluation of any pulmonary cystic malformations, particularly when bilateral.

Abstract
BACKGROUND AND PROCEDURE Pleuropulmonary blastoma (PPB) identifies different types of pulmonary tumors in the pediatric age. It is extremely uncommon and is known to have a very poor prognosis, with only few cases surviving after 10 years follow-up. Our experience with such a patient and long-term follow-up (12 years) is therefore of interest. She was a 2-year-old girl admitted with a history of respiratory distress and underwent a left thoracotomy. The tumor was removed and after 1 month a polychemotherapy course was started using dactinomycin and vincristine for 6 months. The patient remains disease-free 12 years after the operation. CONCLUSIONS The biologic behavior of the tumor is considered unpredictable, and for this reason much effort has been expended in trying to identify prognostic factors. The preoperative size of the mass (size <5 cm) in our patient, its complete excision, and the histologic aspects might be helpful in identifying favorable prognostic factors.

Abstract
BACKGROUND Pleuropulmonary blastoma (PPB) is a unique dysontogenetic neoplasm of childhood. Its primitive, sarcomatous features are analogous to those of other dysembryonic or dysontogenetic tumors, such as Wilms tumor, hepatoblastoma, neuroblastoma, and embryonal rhabdomyosarcoma. PPB typically presents in young children, most younger than 5 years, as a pulmonary and/or pleural-based tumor with cystic, solid, or combined cystic and solid features. These neoplasms are characterized histologically by primitive mesenchymal or a mixture of primitive and sarcomatous components and generally have an unfavorable clinical outcome: death occurs within 1-2 years after diagnosis. METHODS Clinicopathologic and radiographic findings of a man age 36 years with a cystic and solid mass in the left hemithorax were reviewed and compared with previously studied cases of PPB. RESULTS Pathologic examination of the mass revealed a cystic and solid neoplasm composed of malignant mesenchymal cells that were immunoreactive for vimentin and muscle specific actin and focally for desmin. The architectural and cytologic appearances as well as the immunohistochemical profile were those of type II PPB. CONCLUSIONS To the authors' knowledge, all previously reported cases of PPB occurred in children age 12 years or younger. They believe that this case represents the first occurrence of PPB in an adult and documents the finding that, although it is uncommon, adults can develop primitive neoplasms that are usually associated with the pediatric population. In addition, the clinicopathologic features observed in the authors' adult patient were consistent with their experience with this tumor type in children. The patient died less than 1 year after diagnosis.
