Objective:
To improve the diagnosis and treatment of pulmonary carcinosarcoma.
Method:
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.
Result:
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.
Conclusion:
This tumor may be misdiagnosed as brondrogeuic carciniose preoperatively. It tends to metastasize early and prognosis is poor. Surgical intervention is the first choice.
