Abstract
A case of superficial, spreading-type and elevated early gastric carcinoma developing in the upper third of the stomach was recently encountered.
The patient, a 60-year-old man, was found to have a gastric abnormality by mass gastric examination performed in his company on february 2, 1983. Gastric radiologic and endoscopic findings revealed a coarse granular, tuberous and elevated lesion spreading to the cardiac part centering on the small curvature of the posterior gastric wall. Biopsy histologic findings showed a well-differentiated adenocarcinoma. Samples of excised stomach revealed an elevated lesion measuring 9.6×6.4cm, which spread over the posterior and anterior walls of the stomach from the cardiac part to the lower part centering on the small curvature of the corpus ventriculi. The depth of infiltration was m in the entire involved area except for a portion reaching sm, and the entire carcinoma nest was located in the middle zone. Histopathologic findings showed well-differentiated papillary-duct-like adenocarcinoma.
The area of the lesion was large, 61.4cm2, the infiltration to a depth of sm was in only a small part of the lesion and the main location of the lesion was the C area and middle zone area. As these characteristics are different from those in other cases of elevated, superficial and spreading-type carcinoma previously obtained in our department, this case seems useful for investigation of variation in development of gastric carcinoma.
