Pathology of Primary Leiomyosarcoma of the Lung

Dr Sampurna Roy MD      


Leiomyosarcomas are the most common mesenchymal tumors of the lung presenting as an endobronchial lesion with symptoms of obstruction.

Peripheral lesions are asymptomatic.

Histologic grade may be the most reliable prognostic parameter for predicting clinical behavior in primary leiomyosarcoma of the lung and that smooth muscle actin is the most sensitive immunohistochemical marker for establishing the diagnosis in these tumors.

Primary leiomyosarcoma should be considered in the differential diagnosis of pulmonary spindle cell neoplasms.
