Abstract
Carcinosarcoma of the lung is a rare malignancy consisting of both epithelial and mesenchymal components. Although metastatic disease is common, metastatic disease to the small intestine is rare and has been reported only once in the literature. An unusual case of pulmonary carcinosarcoma with metastasis to the small bowel is presented. At the time of laparoscopic exploration, a 4 x 4 cm mass was seen in the jejunum involving the adjacent mesentery. The affected small bowel and mesentery were resected laparoscopically and bowel continuity was restored through an entirely intracorporeal technique. Laparoscopic small bowel resection can be performed safely in the setting of malignant disease and imparts many of the benefits of minimally invasive surgery.

Abstract
Pleomorphic (spindle) cell carcinoma, also known as monophasic sarcomatoid carcinoma, is a rare primary pulmonary malignancy. This type of tumor shows concurrent presence of malignant epithelial and homologous sarcomatoid spindle cell components by co-expressing cytokeratin and vimentin in various degrees. Sixteen cases (four central endobronchial lesions and 12 peripheral parenchymal masses) were studied clinicopathologically. Men were affected far more frequently than women (13:3). The patients were between 56 and 80 years of age. The disease is strongly associated with smoking. Among seven of the patients who underwent surgical resection, four of them had mediastinum, pleura and chest wall invasions, and three of them had regional lymph node metastases. All of the patients succumbed to early distant metastases (range 2 weeks-5 months) in organs including brain, bone, adrenal gland, and unusual sites such as esophagus, jejunum, rectum and kidney. The remaining nine inoperable cases were late stage disease and treated with chemoradiotherapy with little effect. The median duration of survival was 3 months. All parenchymal masses appeared as cavities with marked central necrosis, and only peripheral rim of tumor cells was left. More definite diagnostic results will depend on further tissue sections and can be confirmed by immunohistochemical studies. Significantly fewer Ki-67, p53 and c-erb B-2 oncoprotein expressions were also noted.

Abstract
Carcinosarcoma is a malignant tumor having a mixture of carcinoma and sarcoma containing differentiated mesenchymal elements, such as malignant cartilage, bone, and skeletal muscle. These tumors have been linked histogenetically to pleomorphic carcinomas; it is unclear whether their clinical behavior is significantly different. To investigate this issue, we studied 66 cases of carcinosarcomas of the lung and compared them with cases from a previously published series of pleomorphic carcinomas. Carcinosarcomas show a male-to-female ratio of 7.25:1, with a mean and median age of 65 years. They most often present as solitary masses in the upper lobes and average 7 cm in diameter. Most (62%) were endobronchial or central tumors, whereas 38% were described as peripheral. The most frequent epithelial component was squamous cell carcinoma (46%), followed by adenocarcinoma (31%) and adenosquamous carcinoma (19%), whereas sarcomatous elements most frequently included rhabdomyosarcoma, chondrosarcoma, osteosarcoma, or combinations of these elements. Survival of patients with carcinosarcomas of lung was poor, with a 5-year survival rate of 21.3%. Of several clinical and pathologic parameters, only increased tumor size (with 6 cm as the optimal cutoff point) appeared to be related to reduced survival (p = 0.0195). In comparison with patients with pleomorphic carcinoma, patients with carcinosarcomas had no significant difference in the size of their tumors (p = 1.0), stage at presentation (p = 0.883), location in the lung (p = 0.073), or their overall survival (21.3% vs 15.0%) (p = 0.1038). A significantly greater proportion of patients with carcinosarcoma had squamous cell (p = 0.004) or adenosquamous (p = 0.016) carcinoma, whereas patients who had pleomorphic carcinoma showed a significantly greater frequency of adenocarcinoma (p = 0.029) and large cell carcinoma. The histologic differences between these two types of tumor suggest that they may be different entities with similar behavior, but additional studies are warranted to investigate this hypothesis.

Abstract
A case of pulmonary carcinosarcoma in a 68-year-old male patient is reported. The tumor in the resected left upper lobe extended mainly endobronchially, invading the normal bronchial lumina and mucosa. The carcinomatous component consisted of poorly differentiated squamous cell carcinoma and was mainly located in the periphery of the tumor nests. The sarcomatous component consisted of chondrosarcoma and was mainly located in the center of the tumor nests. Tumor cells in the sarcomatous component reacted with anti-S-100 protein antibody and were surrounded with abundant homogeneous extracellular matrix staining positively with Alcian blue. The transition from the carcinomatous component to the sarcomatous component appeared to be very smooth. The tumor cells in both the carcinomatous and sarcomatous components reacted with anti-epithelial membrane antigen antibody. Ultrastructurally, the tumor cells with tonofibrils in the carcinomatous component were apposed and connected to each other by desmosomes. By contrast, in the sarcomatous component, the tumor cells had well-developed and dilated rough endoplasmic reticulum and were arranged loosely in a myxomatous matrix. Some tumor cells in the sarcomatous component had occasional tonofibrils, and were apposed and connected to each other by desmosome-like structures. It is shown for the first time, ultrastructurally and immunohistochemically, that the tumor cells in the sarcomatous component of pulmonary carcinosarcomas have features of both epithelial and mesenchymal cells. It is suggested that the sarcomatous component in the present case is derived from the carcinomatous component.

Abstract
Six primary lung tumors with numerous multinucleated osteoclast-like giant cells (OLGCs) and no osteogenic component were evaluated histologically and immunohistochemically to examine pulmonary lesions inciting an OLGC response. The patients comprised four women and two men ranging in age from 61 to 80 years (average age, 69 years). The tumors consisted of one adenocarcinoma, two sarcomatoid carcinomas, and three giant cell variants of malignant fibrous histiocytoma. One tumor was endobronchial in location, while five were situated peripherally. Tumor diameter spanned from 1 to 6.5 cm (average, 2.7 cm). In addition to the giant cells, common characteristics included the malignant nature of the neoplasms and, in five of six cases, histologically malignant mesenchyme. This array of cases exemplifies the variability of lung lesions which may elicit an OLGC inflammatory response resulting in areas resembling the giant cell variant of malignant fibrous histiocytoma. The results of this study suggest that OLGCs occur preferentially in malignant rather than benign nonosteogenic lung tumors and that sarcomatoid regions of malignant tumors are more likely to be infiltrated by OLGCs than epithelial regions.

Abstract
The majority of lung neoplasms are malignant. Many of these are central and have an associated endobronchial component. Most such neoplasms are of surface epithelial origin; however, neoplasms of submucosal gland, mesenchymal, and lymphoreticular origin may also demonstrate an endobronchial component. Because of their endobronchial location and associated symptoms, these patients often present at an earlier stage than purely parenchymal lung malignancies. The radiographic features in such cases may be similar to those associated with benign endobronchial tumors; however, there are certain radiological signs that are more suggestive of a malignant process. Despite these circumstances, conservative management such as endoscopic excision are inappropriate in most instances. The clinicopathologic and radiological features of these lesions are detailed.

Abstract
True pulmonary carcinosarcoma (squamous cell carcinoma and chondrosarcoma) originating in the right lower lobe in a 62-year-old Japanese male is reported. The tumor, measuring 5.5 x 3.5 x 3.5 cm, was markedly necrotic and its apex protruded into the bronchial lumen. Light microscopy showed that the tumor was composed of squamous cell carcinoma with sarcomatous spindle or polygonal cell proliferation and true chondrosarcoma. Immunohistochemically, the cytoplasm of numerous cells of the squamous cell carcinoma component was stained with anti-cytokeratin (PKK 1) and the cytoplasmic membrane with anti-epithelial membrane antigen (EMA). Although sarcomatous regions were stained with anti-vimentin (vimentin) and no tumor cells were reactive for EMA, a few tumor cells were positive for PKK 1. The cytoplasm of numerous chondrosarcoma cells was positively stained for vimentin and S-100 protein. Based on these findings, we concluded that the present tumor was a true carcinosarcoma composed of squamous cell carcinoma with sarcomatous regions and true chondrosarcoma.

Abstract
The histological distinction between carcinosarcoma and mesothelioma has received little attention. The object of this study was to describe the histology and immunohistochemistry of two carcinosarcomas presenting as pleural tumours. These were compared with 12 carcinosarcomas from sites within the lung, and with the established features of mesothelioma. Histologically and immunohistochemically, these 'pleural' carcinosarcomas are similar to conventional pulmonary carcinosarcomas but accurate recognition is hindered by their gross appearance and biphasic histology which closely mimic mesothelioma. They may exhibit features such as neutral mucin, expression of carcinoembryonic antigen, squamous differentiation, and neuroendocrine differentiation which, when present, are evidence against mesothelioma. These tumours are rare and have passed unnoticed until now.

Abstract
True carcinosarcoma of the prostate is a rare neoplasm, with only 9 cases well documented by immunocytochemistry and ultrastructural examination. We report a case of an unresectable pelvic tumor studied at autopsy. The primary prostatic neoplasm and pulmonary metastases were composed of well differentiated adenocarcinoma admixed with foci of leiomyosarcoma and osteosarcoma. The sarcomatous components showed reactivity with vimentin and desmin, did not express prostatic acid phosphatase (PAP) and prostate specific antigen (PSA), and contained myofilaments on electron microscopic examination. Positive staining of the carcinomatous component for PAP and PSA was noted. These findings confirm the mixed epithelial and mesenchymal components in primary and metastatic sites, and support the diagnosis of true prostatic carcinosarcoma.

Abstract
Eight primary carcinomas of the lung with a prominent spindle-cell sarcomatoid component were studied by immunocytochemical staining and electron microscopy. The eight tumors were indistinguishable by conventional light microscopy, with the exception of one unusual neoplasm that followed multiple pathways of differentiation with elements of squamous cell carcinoma, rhabdomyosarcoma, chondrosarcoma, and an undifferentiated spindle-cell population. Reticulin fiber production by individual spindle cells and a sharp demarcation of the carcinomatous and sarcomatoid domains by light microscopy were not useful differentiating features. Three of the eight tumors exhibited keratin expression in both the carcinomatous and spindle-cell components. Both immunocytochemical and electron microscopic analyses were required to detect epithelial differentiation, as in one case keratin was identified only by immunocytochemical staining and in another only by ultrastructural examination. Epithelial differentiation was undetectable in the sarcomatoid component of five tumors, and in one case immunoreactive myoglobin was identified in spindle cells; skeletal muscle differentiation was confirmed ultrastructurally. We propose that pulmonary carcinomas exhibiting evidence of epithelial differentiation in a sarcomatoid component be termed spindle-cell carcinomas and that those biphasic tumors exhibiting mesenchymal differentiation into specific tissues, such as neoplastic bone, cartilage, or striated muscle, or lacking epithelial differentiation by light microscopy, immunocytochemistry, and electron microscopy be classified as carcinosarcomas. This distinction may ultimately be unnecessary, because these two tumors may represent different points along a morphologic and biologic continuum.

Abstract
A unique case of carcinosarcoma of the colon is reported. The tumor invaded the bowel wall deeply, metastasized widely, resisted multi-agent chemotherapy, and caused the patient's death 4 years later. The tumor was composed of adenosquamous carcinoma admixed with sarcoma showing osseous, cartilaginous, and nonspecific spindle-cell differentiation. Although carcinoembryonic antigen appeared limited to carcinoma cells, cytokeratin immunoreactivity was observed in both carcinoma and sarcoma cells. Like carcinosarcomas at other body sites, the finding of cytokeratin in sarcoma cells supports partial epithelial differentiation in this component, likely retained from carcinoma precursor cells.

Abstract
The clinical presentation, clinical course, and results of various treatment modalities of 17 patients with carcinosarcoma of the lung were reviewed. This group of patients was 0.2% of all Mayo Clinic patients with lung cancer who had been treated between 1971 and 1982. Most patients were men in the sixth decade of life who had a history of smoking. Ten of 17 neoplasms were located in the upper lobes. Noninvasive diagnostic tests had a low yield in detecting carcinosarcomas. Pulmonary resection with curative intent was performed in 15 of 17 patients; however, only 4 patients were alive at 6, 8, 28, and 39 months, respectively, postoperatively. The median survival was 1 year. Doxorubicin-based chemotherapeutic programs produced an objective response in two of four patients.

Abstract
An autopsy case is presented in which a pulmonary carcinosarcoma filled the left chest of a 61 year old man. The extensive pleural involvement that this neoplasm exhibited has not been reported previously. By light microscopy the neoplasm initially was considered a mesothelioma because of the pattern of glands and undifferentiated sarcomatous stroma. However, by electron microscopy the sarcomatous component was found to show rhabdomyoblastic differentiation. Neither histochemical stains nor electron microscopy supported a mesothelial origin for the glandular component. Differential diagnostic considerations of pleuropulmonary neoplasms showing rhabdomyosarcomatous differentiation are discussed. This case illustrates the importance of detailed study in order to characterize and properly classify these neoplasms.
