  • Abstract
  • Look Inside

 A 43-year-old female complained of a palpable lower abdominal mass in May, 1972, which was diagnosed as gastric carcinoma by means of x-ray examination of the stomach and gastrofiberscopy. The tumor rapidly increased in size to occupy the entire abdominal cavity in Novenmber and she died on Nov. 30, 1972.

 Autopsy revealed a gastric carcinoma, located over the entire circumference of the gastric antrum, which showed massive direct invasion into the major omentum measuring 27×21×12 cm in size. On the cut surface the tumor mass in the major omentum showed almost entirely hemorrhagic necrosis. No continuous invasion into other organs except for the transverse colon was noticed.

 Histologically, the gastric carcinoma was well-differentiated tubular adenocarcinoma, partly with prominent papillary proliferation and hemorrhagic necrosis in the omental tumor mass.

 Several, up to fist-sized metastatic nodes were seen in the liver, where they were medullary and also showed hemorrhagic necrosis. One of the lymph node metastases showed signet-ring cell carcinoma. No peritoneal dissemination was seen.

 There was no definite evidence of choriocarcinoma so far as was examined.
