A case of esophageal carcinosarcoma / 대한내과학회지

ABSTRACT

Carcinosarcoma of the esophagus is a rare malignant neoplasm that consists of both carcinomatous and sarcomatous components, accounting for approximately 1~2% of all esophageal neoplasms. The terms previously used to describe this tumor include pseudosarcoma, pseudosarcomatous carcinoma, polypoid carcinoma, so-called carcinosarcoma, true carcinosarcoma, and spindle cell carcinoma. Although about 11 cases of esophageal carcinosarcoma have been reported in Korea, none have included findings from positron emission tomography. Here, we report a case of esophageal carcinosarcoma in a 63-year-old man who presented with a 3 month history of progressive dysphagia and weight loss. Positron emission tomography shows expanding hot uptake (mSUV, 9.94) in the distal esophagus.
