  • Abstract
  • Look Inside

 On Feb. 4, 1986, during a mass survey at our hospital, a 45 year-old woman was noticed to have a gastric abnormality. She was subjected to further examinations.

 X-ray and endoscopic examinations (Figs. 1 a ~ c, 2 a, b) showed a protruded lesion on the posterior wall of the upper corpus, irregular thickening of folds on the anal side of a polypoid lesion, and narrowing of the lumen of the stomach. The diagnosis made was that of gastric cancer of Borrmann type 1 + 4, and total gastrectomy was performed on March 4, 1986.

 Pathological study revealed a relatively small lesion (3.3 × 2.7 cm) and a vast submucosal or deeper invasion of undifferentiated carcinoma cells, which are common findings in linitis plastica type of gastric cancer (Figs. 3 ~ 5, 6a ~ c).

 The characteristic feature of this case was the polypoid lesion in the center of the primary lesion.

 Although the origin and growing process of linitis plastica is still controversial, recent studies5) explain it as a small superficial carcinoma in the fundic gland mucosa, usually of depressed form. It infiltrates the submucosa extensively before a cancerous ulceration is formed. Many reported cases of linitis plastica seem to support this theory and most of them describe a depressed lesion as the primary lesion.

 Our case, too, is no exception to this theory, and pathologically, it was diagnosed as linitis plastica. It is reported here because of the rarity of the polypoid-type lesion in the primary lesion of linitis plastica gastric cancer.
