The pulmonary carcinosarcoma is a rare malignant tumor, which composed of an admixture of histologically malignant epithelial and mesenchymal tissues. Carcinosarcomas comprise 0.2% of all pulmonary neoplasms and are most often found in a proximal bronchus. We report two cases of the pulmonary carcinosarcoma with a rewiew of the literatures.

Carcinosarcoma is an unusual and rarest neoplasm in man, consisting of carcinomatous parenchyme and sarcomatous stroma. Two clinical types of carcinosarcoma were present. One type of tumor was centrally located [endobronchial type], infrequent metastasis, and better prognosis than parenchymal type. The other type was peripherally located [parenchymal type], frequent metastasis, and poor prognosis. The histogenesis of carcinosarcoma is many hypothesis, but controversial; 1] sarcomatous degeneration of stroma, 2] intermingling of simultaneously arising carcinoma & sarcoma, 3] multiple primary tumor, 4] blastomatous changes in hamartoma, 5] stromal reaction to squamous cell carcinoma, 6] true & collision carcinosarcoma. In this case, 52 year-old male patient was hospitalized due to intermittent hemoptysis & known pulmonary lesions. Since 1968, chest PA showed round haziness within cyst & multiple cyst on RUL & RLL. Radical pneumonectomy was performed and histopathology showed carcinosarcoma, surrounded by bronchial epithelium. The patient maintain general well-being without clinical evidence of recurrence till now.

Carcinosarcoma of the lung is an admixture of cardinomatous and sarcomatous lesion and accounts for 0.3% of all pulmonary neoplasm. Clinicopathological features are often related to anatomical location : central endobronchial type and peripheral parenchymal type. Noninvasive diagnostic tests had a low yield in detection carcinosarcoma. Metastasis to regional lymph nodes and to distant organ is common. The prognosis is poor and the median survival is less than one year.Two cases of carcinosarcoma patients are reported here - one case is composed of undifferent cell carcinoma and spindle cell sarcoma in the male of 72 year old and the other case squamous cell carcinoma and spindle cell sarcoma in the male of 65 year old.

Carcinsarcoma is an uncommon pulmonary malignancy characterized by carcinmatous parenchyma and sarcomatous stroma. The cytologic, immunohistochemical and ultrastructural features of a case of pulmonary carcinosarcoma suspected by fine needle aspiration cytology is presented. Only bizarre spindle cells arranged in loose groups, in microtissue fragments and in a dissociate fashion were present on the aspiration smears. They were markedly positive for vimentin. The epithelial component was not found, which was probably due to marked paucity of carcinomatous component that was proved by histologic examination of the resected tumor. The diagnosis of pulmonary carcinosarcoma should be conidered whenever poorly differentiated epithelial ceil groups with a malignant mesenchymal component set in a myxoid background are seen in a pulmonary cytology specimen.

Carcinosarcoma of the lung is a rare turner with an admixture of malignant epithelial(carcinomatous) and malignant mesenchymal (sarcomatous) components. Clinicopathologically, pulmonary carcinosarcoma has been divided into two types by its anatomical locations and growth nature, peripheral parenchymal and central endobronchial variants. We experienced an endobronchial carcinosarcoma that induced complete atelectasis of the right lung due to polypoid growing mass from the right upper lobe bronchus in a 67 year old male smoker. The patient underwent a successful right pneumonectomy. The tumor was composed of squamous cell carcinoma with variable sarcomatous differentiation into myogenous and undifferenciated sarcoma that demonstrated by immunohistochemical study. The patient has been doing well for the last seven months since the operation, without metastases or turner recurrence.

폐의 암육종은 상피조직과 간염조직이 혼재하는 악성종양으로 전체 폐종양의 0.3%에 불과한 매우 희귀한 종양이며 흡연과 깊은 관계가 있는 질환이다. 폐에서의 위치에 따라 비교적 예후가 양호한 endobronchial type과 빠른 원격전이로 예후가 불량한 solid parenchymal type으로 분류된다. 비침습적 진단방법으론 발견이 어렵고 생검에 의해 종종 발견된다. 폐문과 종격동으로 전이를 잘하며 광범위 절제가 치료의 기본이고 항암제 요법을 병용하기도 한다. 암육종의 예후는 매우 불랑하여 술후 평균생존 기간은 9개월 정도이고 2년까지 생존율은 10% 미만인것으로 보고 된다.

A 45-year-old male was admitted to Department of Thoracic Surgery, Korea University Hospital with the chief complaints of cough and high fever of two months duration. His chest roentgenogram revealed homogenous ill-defined increased density in right lower lung, and bronchogram showed the abrupt cut-off sign of the proximal portion of the right intermediate bronchus. Preoperative evaluation of this patient revealed no contraindication of the pulmonary surgery. So Radical Right pneumonectomy was performed under the preoperative impression of lung cancer. And post-operative course was uneventful. Pathologic examination of the resected lung revealed Carcinosarcoma without regional lymphnode metastasis.
