Carcinosarcomas of the esophagus are rare malignant neoplasms that consist of both carcinomatous and sarcomatous components, which comprise approximately 1~2% of all esophageal neoplasms. Usually, esophageal carcinosarcomas are the polypoid type, and patients with esophageal carcinosarcoma have progressive dysphagia. The multiplicity in terminology appears to be related to the uncertain histogenesis of these tumors. We report a case of a polypoid esophageal carcinosarcoma with a spontaneous resected stalk in a 45 year-old male patient who presented with progressive dysphagia and weight loss.
