Leiomyosarcoma of the bronchus. Report of a case

Primary bronchopulmonary leiomyosarcoma of the left main bronchus in a child presenting with wheezing and atelectasis of the left lung

Primary lung tumors are rare in children, and primary bronchopulmonary leiomyosarcomas are very rare in children, with only 10 cases reported in the English-language literature. We report on the eleventh case of primary bronchopulmonary leiomyosarcoma in a child, and it is the first case in Taiwan, and also in Asia. In addition, this is the second case of this tumor arising in the left main bronchus. Before the present case, there were only 2 cases of this tumor in the main bronchus: one was in the right main-stem bronchus, and the other in the left-stem main bronchus. Ours is the second case showing pleural effusion. Chest roentgenogram and bronchoscopy are helpful in the diagnosis of primary bronchopulmonary tumors, but a definitive diagnosis can only be made by biopsy. The tumor is potentially curable if total excision is possible; irradiation has little therapeutic value, and early excision offers the only hope of cure. The child is alive and well 19 months after pneumonectomy, without having received radiotherapy or chemotherapy.

Primary pulmonary leiomyosarcoma. Review of the literature and report of a case

In a review of the literature, 38 cases of pulmonary leiomyosarcoma were found. An additional case with highly progressive course is reported and the diagnostic and therapeutic possibilities are discussed. Prognostic signs are evaluated. The importance of radical surgery is emphasized.

Primary leiomyosarcoma of the lung

Ramanathan, T. (1974).Thorax, 482-489. Primary leiomyosarcoma of the lung. Three new cases of primary leiomyosarcoma of the lung are presented. The relevant literature has been reviewed. The similarity in the clinical features between bronchogenic carcinoma and leiomyosarcoma is emphasized. The only distinctive feature of leiomyosarcoma is the absence of lymph node involvement.

Complications during removal of a pedunculated endobronchial leiomyosarcoma

Pedunculated endobronchial leiomyoma or leiomyosarcoma is comparatively rare and is known to produce intermittent, partial or complete obstruction of the ipsilateral lung. Rarely it causes obstruction of the contralateral main bronchus. Fatalities have been caused by obstruction of the contralateral main bronchus during surgery. A pedunculated intrabronchial leiomyosarcoma obstructing the contralateral main bronchus is reported.
