Abstract

Sarcomatoid carcinoma of the stomach is a rare type of malignant tumor, characterized by distinct cellular morphology. This type of tumor is even more rare in giant size. The present study reports a case of giant sarcomatoid carcinoma, which developed in the distal stomach. A 49-year-old male underwent medical investigation for gastrointestinal hemorrhage. Endoscopic examination, computed tomography (CT) and positron emission tomography-CT scan identified a giant neoplasm, which involved the gastric antrum and body, gallbladder and hepatic flexure of the colon. Surgery was performed to excise the tumor, which was ~14x13x8 cm in size. A diagnosis of sarcomatoid carcinoma was made since the tumor was positive for epithelial markers, even within the mesenchymal elements. To the best of our knowledge, only 5 cases of sarcomatoid carcinoma of the stomach have been previously reported, and a tumor that has been able to be resected despite such a large size has never been reported.
