Abstract
In this report we describe a choristoma in the lung of a female placebo rat. The lesion was observed microscopically in the central part of the left lung lobe and was characterized by a nodule consisting of well-differentiated skeletal muscle cells. The muscle fibers were haphazardly organized giving the nodule a poorly demarcated border. Choristoma is a very rare lesion.

Abstract
Rhabdomyosarcoma arising within a congenital cystic adenomatoid malformation (CCAM) is an unusual entity. The patient underwent a lobectomy of his right lower lobe of lung due to a CCAM at the age of two. One year later, he developed a solid embryonal rhabdomyosarcoma at the same location. He received 1-year period chemotherapy and when the tumor reduced to a resectable size, surgical excision was done. The tumor cells appeared more differentiated after chemotherapy. The patient remains disease free to date, 16 months after surgery.

Abstract
This article provides a broad overview of tumors that can involve the tracheobronchial tree. For the most part, the clinical, radiographic, and endoscopic presentation of these rare tumors does not differ significantly from the more common tumors of the lung. Appropriate classification of many tracheobronchial tumors ultimately requires complete sampling and a thorough microscopic evaluation. The introduction of ancillary diagnostic techniques such as immunohistochemistry and molecular analysis will continue to refine tumor classification.

Abstract
The current report describes a 13-month-old boy with primary pulmonary rhabdomyosarcoma (RMS) that originated within a congenital cystic adenomatoid malformation (CCAM). To the best of our knowledge, he is the youngest patient of all primary pulmonary RMS cases reported in the English-language literature. The tumor, localized in left upper lobe, was removed completely, and histologic examination showed embryonal subtype. Postoperative systemic chemotherapy was carried out. Recent evaluation 15 months after resection has not identified any residual or recurrent disease. Primary pulmonary RMS, although very rare in the pediatric age group, should be considered in young patients with solitary pulmonary masses and associated cystic lesions.

Abstract
A type I congenital cystic adenomatoid malformation (CCAM) in the left lower lobe was removed from a 11-year-old boy with a 3-month history of recurrent pneumonia. As incidental finding, a bronchioloalveolar carcinoma (BAC) was found in the lung parenchyma adjacent to the cyst. A left lower lobectomy was performed. At 18 months after surgery the patient is well and free of neoplastic disease. To the best of our knowledge, this association has not been reported previously in a pediatric patient. Malignancies complicating CCAM are rarely seen, but have been reported in adults. Including our case, eight cases of BAC and five cases of rhabdomyosarcoma (RMS) in association with CCAM have been reported so far. As CCAM can host metaplastic mucous cells, primitive mesenchymal cells and differentiated but poorly organized striated muscle fibers, it has been proposed that CCAM may act as a predisposing condition for oncogenesis. Our experience adds further support that CCAM can act as a premalignant lesion. Previous reports of both BAC and RMS in asymptomatic CCAM suggest prompt resection shortly after diagnosis.

Abstract
The cases of two children under three years of age with primary pulmonary rhabdomyosarcoma and no associated lung malformations are reported and a review of the literature is presented. In both, complete surgical removal of the tumor was performed and histologic examination revealed embryonal subtype. Flow cytometric assessment showed a tumor-cell diploid DNA content. Postoperative radio- and chemotherapy were carried out, but in spite of treatment both girls died because of disease progression, fourteen and nine months after diagnosis. The importance of associated cystic lung malformations and DNA content in predicting clinical outcome of primary pulmonary rhabdomyosarcoma is evaluated.

Abstract
The case of a 22-month-old boy with alveolar rhabdomyosarcoma of the lung is presented. Brain metastasis and recurrence of the right pulmonary hilum and parietal pleura developed 6, 11, and 24 months (respectively) after tumor resection. Chemotherapy and radiotherapy were effective. Neuron-specific enolase was very helpful in detecting metastasis and disease recurrence. Primary pulmonary rhabdomyosarcoma can be divided into two groups: tumor in the normal lung, and tumor in cystic lesions of the lung.

Abstract
We reviewed the clinical course and the results of various treatment modalities of 80 patients with rare pulmonary neoplasms, who constituted 0.8% of all patients with primary lung cancer treated at the Mayo Clinic from 1980 through 1990. The 50 male and 30 female patients had a median age of 60 years (range, 20 to 87). The histopathologic types of these rare pulmonary neoplasms were non-Hodgkin's lymphoma (41%), carcinosarcoma (20%), mucoepidermoid carcinoma (15%), malignant fibrous histiocytoma (5%), malignant melanoma (4%), fibrosarcoma (4%), leiomyosarcoma (4%), angiosarcoma (2%), hemangiopericytoma (2%), osteosarcoma (1%), and blastoma (1%). Follow-up was complete in all 80 patients, and the median duration of follow-up was 59 months (range, 15 to 130). Of the 80 patients, 63 (79%) underwent pulmonary resection. Of the other 17 patients, 8 underwent only bronchoscopy for diagnosis, 4 had unresectable disease at thoracotomy, 3 had metastatic disease on initial assessment, and 2 had mediastinal involvement detected on mediastinoscopy. Fifty-four patients (68%) received chemotherapy or radiation treatment (or both). The overall 5-year survival was 39%. The strongest factors that influenced survival were cell type and extent of disease at time of initial examination.

Abstract
Over the past 9 months, three cases of primary pulmonary rhabdomyosarcoma have been treated at British Columbia Children's Hospital. Two patients (aged 24 and 37 months) presented with spontaneous pneumothoraces and had cystic changes in the affected lung on chest radiograph. The third patient (aged 42 months) was evaluated for chronic cough, fever, and failure to thrive. Chest x-ray showed a large mass in the left lower lobe as well as mediastinal adenopathy. All three of these lesions originated within congenital lung cysts, one a peripheral bronchogenic cyst and the others cystic adenomatoid malformations. This report suggests that there is a significant risk for the development of rhabdomyosarcoma within malformed pulmonary tissue.

Abstract
Primary lung tumors are uncommon in children, and malignant mesenchymal tumors form only a small proportion of these. Leiomyosarcomas occur more commonly than rhabdomyosarcomas, whereas malignant mesenchymomas are exceedingly rare. Of the total number of primary pulmonary rhabdomyosarcomas and malignant mesenchymomas of lung reported in children, 50% have occurred in association with congenital lung cysts. The relationship between abnormal morphogenesis and neoplasia is well documented in the kidney. A similar relationship may exist in the lung between cystic parenchymal maldevelopment and embryonal mesenchymal tumors. We report a 4-year-old boy with a malignant mesenchymoma of lung arising within a congenital lung cyst; one similar case has previously been reported to our knowledge.

Abstract
A unique case of embryonal rhabdomyosarcoma arising at the left pleura of a 7-year-old Japanese girl is reported. The present case was characterized by persistent pleural effusion, and the malignant cells incidentally found in it were the first diagnostic clue. The tumor showed a rare growth pattern involving diffuse thickening of the parietal pleura. Biopsy of the thickened parietal pleura upon thoracotomy revealed embryonal rhabdomyosarcoma largely composed of immature mesenchymal cells. Immunohistochemical demonstration of creatinine phosphokinase-MM was most helpful among several types of immunostain for the histopathological diagnosis. Ultrastructurally, thin filaments with primitive Z bands could be seen in some tumor cells. Intensive clinical examination revealed only diffuse thickening of the parietal pleura, which was reduced by chemotherapy. This is the first documented case of rhabdomyosarcoma arising at the pleura. Previous reports of rhabdomyosarcoma arising at unusual sites are reviewed and the histogenesis of this tumor is briefly discussed.

Abstract
In children, primary tumors of the lung constitute a unique subset of quasineoplastic and unequivocally neoplastic lesions whose benign or malignant potential is not always predictable on the basis of morphologic findings. One such neoplasm in the latter category is the primary bronchopulmonary fibrosarcoma (PBPF). This clinicopathologic, ultrastructural, and immunohistochemical study documents our experience with five PBPFs in newborns and children up to 11 years of age at diagnosis. The tumors were either endobronchial or intraparenchymal in location. A uniform population of interlacing bundles and sheets of densely arranged spindle cells with variable mitotic activity was observed microscopically in each case. Ultrastructurally, the cells had the features of fibroblasts and vimentin was the only immunohistochemical marker identified. Despite the disturbing pathologic findings, the four children with more than 1 year of follow-up have survived well 4 to 9 years after surgical resection. Our results are compared with the 21 cases of PBPF reported in the literature and the differential diagnosis is discussed.

Abstract
A cyst in the left lower lobe of the lung was removed from a 15-month-old girl and showed evidence suggesting a preexistent congenital cystic adenomatoid malformation; in addition a rhabdomyosarcoma was identified. Primitive mesenchyme and mesenchymal elements also were seen. The origin of the rhabdomyosarcoma is discussed. The findings in the present case are compared with those of all childhood pulmonary rhabdomyosarcomas reported in the literature. This report of a child with a coexistent congenital adenomatoid malformation and a rhabdomyosarcoma is the third of its kind in the literature.

Abstract
This report describes two cases of pulmonary rhabdomyosarcoma occurring in children, ages 21 and 30 months at diagnosis. Both patients presented with spontaneous pneumothorax and had cystic changes in the affected lung by chest x-ray. Ultrastructural and immunohistochemical studies supported the myogenic phenotype of these neoplasms. The authors were unable to confirm that either of these tumors had unequivocally originated in a congenital cyst although previous authors have reported this association. An apparent morphologic spectrum of embryonic appearing neoplasms including pulmonary blastoma and a malignant mesenchymoma have been observed in the lungs of children.

Abstract
A unique case of pulmonary rhabdomyosarcoma with an isolated, symptomatic small bowel metastasis is presented. The tumor affected the middle lobe, and was treated with a right pneumonectomy. Eleven months after the operation, an isolated small bowel metastasis, which produced intestinal obstruction, was resected. The patient is currently alive, 11 months after operation. The myogenous nature of the tumor was confirmed by the immunohistochemical demonstration of myoglobin in the pulmonary and enteric lesion by the ultrastructural findings of poorly developed sarcomeres.
