A Case of Double Esophageal Carcinoma Along with So-called Carcinosarcoma and Squamous Cell Carcinoma

Abstract

We report a very rare case of double esophageal carcinoma along with so-called carcinosarcoma and squamous cell carcinoma. A 57-year-old man admitted for dysphagia was found in esophageal X-ray and an upper gastrointestinal series to have squamous cell carcinoma in the middle intrathoracic esophagus. The lesion was too narrow to examine from the anal side of esophagus. Metastasis surveys suggested multiple lung metastasis. After undergoing 1 course of chemotherapy and radiation therapy, the man experienced difficulty in swallowing his saliva, necessitating subtotal esophagectomy. Macroscopic and microscopic findings of resected specimens showed squamous cell carcinoma in the middle intrathoracic esophagus and so-called carcinosarcoma in the lower intrathoracic esophagus. So-called carcinosarcoma of the esophagus is a rare malignant neoplasm, hence our report.
