A 55-years old patient is reported who became ill with recurrent attacks of coughing and haemoptysis some 3 weeks before death. An extensive mediastinal tumor was demonstrated radiologically. Pathoanatomical examination showed a pleomorphic rhabdomyosarcoma of the lower left pulmonary lobe with metastases in the right lung and regional lymph nodes.

Primary tumors of the lung rarely occur in children. However, 230 well-documented cases, including the 2 presented in this review, have been identified in the English-language literature. One hundred fifty-one tumors in these reports were classified as malignant lesions and 79 as benign neoplasms. Bronchial "adenomas" constituted the largest group; most of these lesions were of the carcinoid variety, and 8% were definitely malignant. Forty-seven cases of bronchogenic carcinoma were reported in children under 16 years of age, although there were few squamous cell tumors (12%). Fifty-six percent of the benign tumors were classified as inflammatory pseudotumor. Most of the children in this collective series were seen with symptoms related to bronchial irritation or obstruction, such as cough, hemoptysis, atelectasis, or pneumonitis. Respiratory distress was an unusual symptom that was often associated with large tumors seen in the neonatal period. Approximately 20% of the children were totally symptomatic. The limited survival data that are available indicate that leiomyosarcoma and mucoepidermoid carcinoma have a more favorable prognosis in children than in adults. Survival with bronchial carcinoid tumors (90%), bronchogenic carcinoma (30%), and pulmonary blastoma (45%) appears to parallel that for adults. The experience with pulmonary rhabdomyosarcoma, as described in this review, emphasizes the importance of early diagnosis and the use of combined modes of therapy in the approach to these malignancies. Despite the rarity of primary pulmonary neoplasms in children, this diagnosis should be considered in young patients with solitary pulmonary masses or persistent, atypical pulmonary symptoms. It is hoped that early diagnosis will result in an improved prognosis and prevent life-threatening complications.

A case of polypoid sarcoma of the pulmonary trunk is described in an 80-year-old woman who had a 21-year history of episodic chest pain and hemoptysis. Ultrastructural examination revealed Z bands, characteristic of rhabdomyosarcoma, and leptomeric organelles. This is the 60th reported case of sarcoma of the pulmonary trunk. Symptoms in reported cases were variable, usually caused by tumor emboli to the lungs or by right ventricular outflow obstruction. Angiography was diagnostic. The tumor was characteristically polypoid, often multicentric, and by definition was fixed to the pulmonary trunk or valves. Non-differentiated sarcoma (often uniquely pleomorphic) was found in 37% of patients, leiomyosarcoma (once confirmed by electron microscopy) in 17%, myxosarcoma in 13%, elements of rhabdomyosarcoma in 8%, fibrosarcoma in 8%, elements of chondrosarcoma in 11%, and 5% were malignant mesenchymomas. The authors suggest that these tumors originate from the undifferentiated tissues of the bulbus cordis and propose the name myenchymoma for the tumor.

This report describes the first case of rhabdomyosarcoma of the trachea in a 65 year old man with a five week history of cough, wheezing, and hemoptysis. The tumor, presumably originating in the submucosal tissue, was characterized as an intratracheal polypoid mass showing no local invasion or distant metastasis. Rhabdomyosarcoma of the lower respiratory tract and its histogenesis are briefly reviewed and discussed.

Pulmonary artery rhabdomyosarcomas are rare lesions, with a small number of cases reported in the literature. We report a case of pulmonary artery rhabdomyosarcoma that arose in the right pulmonary artery. The patient presented with cough, chest pain, and hemoptysis and was found to have a sarcoma arising in the right pulmonary artery and extending distally within the pulmonary vasculature into the right lung. The gross pathologic features, microscopic appearance, immunohistochemical profile, and computed tomographic and electron microscopic findings are presented. The site of origin and differential diagnosis of these lesions are discussed.

Nine children (6 boys, 3 girls) were diagnosed with a primary endobronchial or pulmonary parenchymal neoplasm. The average age at diagnosis was 9 years. Presenting complaints included cough (7), fever (5), pulmonary infection (3), respiratory distress (3), weight loss (2), pain (2), and hemoptysis (1). Pulmonary x-rays showed persistent atelectasis, pneumonic infiltrates or mass lesions. A computed tomography scan was performed in 8. Five of six endobronchial tumors were diagnosed with bronchoscopy and biopsy. Treatment consisted of thoracotomy and pulmonary resection in 7 cases and laser resection in 2. The pathologic diagnoses were bronchial carcinoid (3), bronchial mucoepidermoid carcinoma (1), inflammatory pseudotumor (plasma cell granuloma) of the bronchus (2) and of the lung parenchyma (1), fibrosarcoma (1), and rhabdomyosarcoma (1). Postoperative chemotherapy was given only to the patient with pulmonary rhabdomyosarcoma; this child died. One child has developed a local recurrence while 7 children are alive and free of disease at an average of 2.4 years postresection. Pulmonary neoplasms are unusual in the pediatric age group and represent a wide spectrum of pathology. Including the present series, 383 tumors have been described. Seventy-six percent were malignant. Early investigation and surgical intervention are essential in children with persistent pulmonary symptoms or x-ray abnormalities. In most cases, the prognosis is excellent with complete surgical resection; however, malignancies other than bronchial adenoma are associated with significantly mortality.

A 9-year-old female presented with fever, cough, and hemoptysis for a week. The chest skiagram and contrast-enhanced computerized tomography delineated a well-defined solid lesion localized to the superior segment of the right lower lobe with features of a congenital pulmonary airway malformation. The lesion was surgically managed with a segmentectomy and histopathology confirmed a contained pulmonary rhabdomyosarcoma (RMS). No other primary site of origin was evident, and a final diagnosis of "primary" pulmonary RMS was made. She received adjuvant chemotherapy and was disease free after 6 years of surveillance. The unique clinicoradiological features of the case are discussed and the sparse literature is reviewed.
