  • Abstract
  • Look Inside

 We report a case of superficially spreading elevated type early gastric cancer which spread in the entire gastric body and fornix with atrophy.

 The patient was a 66-year-old woman who presented with abdominal pain and general fatigue. X-ray and endoscopic examinations revealed a wide flat elevation with some cauliflower-like gross tuberous growth involving the entire gastric body and fornix with atrophy (Figs. 1-5). The boundary of the lesion precisely consisted with the f-line at anal side and the F-line at oral side (Figs. 3-5). Histological examination of the polypectomized specimen obtained from the largest polypoid lesion showed well differentiated papillo-tubular adenocarcinoma (Figs. 6-7).

 Total gastrectomy with extended lymph node dissection (R2) was performed. With Alcian blue staining the lesion was stained darkly, which made the lesion more clearly demarcated (Fig. 9).

 Histological study of the resected specimen revealed well differentiated papillo-tubular adenocarcinoma at the polypoid lesion (Figs. 12-13) and very well differentiated tubular adenocarcinoma at the flat elevated lesion (Fig. 11). The lesions were measured 15.O×11.Ocm in size, with a depth of invasion of m (ly(-), v(-), INFα) and no metastasis was found in the dissected lymph nodes.

 There have been some reports that early gastric cancer of superficially spreading elevated type expands monofocally with the center of the lesion usualy involved as deep as sm layer. However, we did not find sm invasion in all the lesions, suggesting multifocal growth in this case.

 It is known that superficially spreading elevated type gastric carcinoma occurs rarely in comparison with depressed type. Furthermore, our case is distinguished by huge size, 15×11cm in diameter, the largest ever reported so far.
