The patient, male, 47 years old, had a feeling of abdominal discomfort one month earlier. He found a mass in his abdominal cavity, no sign of abdominal pain, blood in the stool, and obstruction of digestive tract. After the examination, he was admitted to the hospital for treatment of “abdominal tumors to be investigated”. Physical examination: normal development, moderate nutrition, superficial lymph nodes are not swollen, heart and lung without exception. The abdomen is slightly raised (after eating), and a large mass can be touched on the right side of the abdomen, right up to the xiphoid process.
