[Carcinosarcoma of the lung clinical analysis].
OBJECTIVE
To improve the diagnosis and treatment of pulmonary carcinosarcoma.


METHODS
Two patients with pulmonary carcinosarcoma were confirmed by operation and pathology were presented and relevant literatures were reviewed. The histo-pathological, clinical features, diagnosis, differential diagnosis and treatment were introduced appearance.


RESULTS
Carcinosarcoma of the lung is rare. It is 0.2%-0.6% of pulmonary malignant tumor. Carcinosarcoma of the lung may be divided into 2 types: First, the endbronchial type which tends to grow slowly in a polypoid pattern along the major bronchi with local invasive feature. The second, arising peripherally which tends to metastasize early with serious outcome.


CONCLUSIONS
This tumor may be misdiagnosed as brondrogeuic carciniose preoperatively. It tends to metastasize early and prognosis is poor. Surgical intervention is the first choice.
