True carcinosarcoma of the esophagus with osteosarcoma.
ABSTRACT We experienced a case of true carcinosarcoma of the esophagus with osteosarcoma. Computed tomography scan revealed calcification of the tumor. Immunohistochemically, vimentin staining was positive, and osteoid formation was found in the sarcomatous portion. It was clear that the lesion contained osteosarcoma of mesenchymal origin, and thus we diagnosed it as true carcinosarcoma.

ABSTRACT: Esophageal carcinosarcoma (ESC) is a rare malignant lesion of the esophagus with controversial characteristics and prognostic factors. Seventeen consecutive patients with esophageal carcinosarcoma were referred to the Center for Esophageal Diseases located in Padua from January 1, 1980 to December 31, 2011. Clinical characteristics, pathological features, treatment and outcome were retrospectively analyzed in a prospectively collected database. Five patients received palliative treatment and one refused surgery; they died of unresected tumor or progression of disease within 0.6-43.5 months after diagnosis. Eleven patients underwent surgical treatment with complete tumor resection; recurrence rate was 80%, leading to death within 2 years after surgery. Only two resected patients are currently alive and free of disease over 20 years after surgery. Our results did not support the better prognosis concept of esophageal carcinosarcoma and suggested the importance of radical esophagectomy with adequate lymph node dissection.

ABSTRACT: Certain tumors of the esophagus that display both sarcomatous and carcinomatous features have long been recognized. The nomenclature, classification, and histogenesis remain controversial and the microscopic differential diagnosis from other esophageal malignancies can be challenging, particularly in small biopsies. In this paper, we review the literature of carcinosarcoma and present two cases of esophageal carcinosarcoma, describing their salient histologic, immunohistochemical, and ultrastructural features. Also, we assess the expression of MDM2 and CDK4 in the carcinomatous and sarcomatous compartments of our cases and we compare them with the expression of these oncogenes in selected cases of esophageal squamous cell carcinoma with prominent stromal reaction. In both of our cases, identification of some epithelial ultrastructural and immunohistochemical features in cells of otherwise sarcomatous phenotype lends support to the common epithelial origin of these neoplasms. Moreover, positive staining for MDM2 and CDK4 in our cases with equally strong reactions in both carcinomatous and sarcomatous elements provides evidence of a role for these molecules in the pathogenesis of carcinosarcoma. In contrast, in cases of squamous cell carcinoma with prominent stromal reaction only the epithelial cells stained strongly for MDM2 and CDK4. These differences in the MDM2 and CDK4 immunohistochemical profile between carcinosarcomas and carcinomas of the esophagus may assist in their differential diagnosis.Experimental and Molecular Pathology 01/2003; 73(3):198-208.

ABSTRACT: Esophageal carcinosarcoma is a rare malignant tumor composing of both carcinomatous and sarcomatous elements. Endoscopic therapy is less invasive and may represent an alternative to esophagectomy for superficial esophageal carcinosarcoma. Here, we report a 61-year-old male who was diagnosed as esophageal carcinosarcoma and underwent endoscopic polypectomy with well tolerance and favorable prognosis. We also present a brief review of the literature.World Journal of Gastroenterology 08/2009; 15(27):3448-50. · 2.43 Impact Factor
