Abstract
We herein report a case of sarcomatoid carcinoma that developed in a remnant stomach. A 76-year-old male with a history of distal gastrectomy for a duodenal ulcer 28 years earlier underwent investigation for a tumor in the remnant stomach. An endoscopic survey showed a round elevated tumor measuring 6 cm in diameter, and a biopsy specimen suggested carcinosarcoma. A total gastrectomy of the remnant stomach was performed, and the excised tumor was identified to be a malignant neoplasm consisting of both carcinomatous and sarcomatous components. A diagnosis of sarcomatoid carcinoma was made since the epithelial markers were positive even in the mesenchymal elements of the tumor. To our knowledge, only 4 cases of sarcomatoid carcinoma of the stomach have been reported in the English literature so far.
