Abstract

A carcinosarcoma of the esophagus is an uncommon malignancy accounting for approximately 1~2% of all esophageal neoplasms. Histologically, both carcinomatous and sarcomatous components are observed. The terms used to describe this lesion include carcinosarcoma, pseudosarcoma, polypoid carcinoma, pseudosarcomatous carcinoma pseudosarcomatous squamous cell carcinoma and a spindle cell variant of a squamous cell carcinoma. It presents as a bulky intraluminal polypoid lesion mainly in the mid to lower esophagus. It often presents relatively early because of its rapid intraluminal growth. Ultimately, the treatment is similar to that of an esophageal carcinoma requiring an esophagectomy for resectable lesions. We report a case of a 64-year-old man with a carcinosarcoma of the esophagus. Endoscopy revealed a 1.5 cm sized polypoid mass located 25 cm from the incisor with friable nature. Radiological studies revealed a bulky polypoid intraluminal mass with a lobulated border, measuring approximately 7 cm in length, in the mid esophagus that expands the lumen in conjunction with the enlargement of the regional lymph nodes. An esophagectomy was performed.
