Example 1. Female, 68 years old. A mass was found in the left abdomen with fever and anorexia of 40 days. B-splenomegaly with disordered internal light spots suggesting a mixed mass. Permeabilization: There is a constant external pressure notch on the side of the large curvature of the stomach, and the gastric body moves to the right, suggesting an extra-tumoral mass. There was no abnormality in the pyelogram. Physical examination: The left mid-abdominal region touched a 20×15cm mass, which was hard, had nodules on the surface, and had poor activity and tenderness. Suspected as mesenteric tumor, exploratory laparotomy on June 29, 1982. During the operation, the tumor with a size of 20×15×10 cm was found to be extremely hard. The surface was nodular and the capsule was intact without infiltrates around the abdomen.
