Gastric Adenoma : Its Clinico-Pathologic and Histopographic Analyses in Relationship with Gastric Carcinoma -Part Ⅰ : Morphological Characteristics-
ABSTRACT
A total of 52 gastric adenomas from 32 resected stomachs were subjected for the extended histoto-pographic study and its clinico-pathologic correlations were made. Group Ⅰ (adenoma alone) comprised 25.0% of whole cases with gastric adenomas, group Ⅱ (separated adenoma and carcinoma in a samejo stomach) 46.9%, and group Ⅲ (microcarcinomatous focus in adenoma) 28.1%. The average age at the time of gastric resection was 57.4 years (32~82 years), but mostly it occurred in the eldery over the age of 60. The majority of adenomas were elevated and sessile, in flat or semiglobal from, and only 21.6% were pedunculated. Two lesions were of depressed type (of Ⅱc). There were usually ovoid (51.4%) or mulberry shaped (29.75), and their surfaces were evenly granular. The size was less than 2cm in 71.2%, and 82.7% of the adenoma were under 3cm in maximum cross. The average size of group Ⅲ was bigger than that of group Ⅰ and Ⅱ. Two thirds of gastric adenomas were located in the antral portion, and exclusively were along the lesser curvature when adenoma was single. The adenoma was mostly multiple (average 1.63 per stomach), and more numerous in group Ⅱ (2.20 per stomach). Hitologically tubular adenoma comprised 94..2% and the reminders were papillary adenoma. S conceptual critique on the usage of atypical epithelial or borderline epithelial lesion was made.
