Another case of serrated adenoma of the stomach

摘要

Adenomas of the stomach are histologically classified into tubular, villous and mixed (tubulovillous) adenoma. In the literature, in two previous studies, only six cases of serrated adenoma of the stomach have been reported. In this communication, we report a newly identified case. The patient presented with gastric complaints. The endoscopic examination showed a pediculated protruding tumour localised in the gastric corpus. Biopsies were reported as tubular adenoma with high-grade dysplasia. A surgical local excision of the tumour was performed. The histological examination revealed elongated fronds with lateral crenated, saw-tooth-like notches as a result of scalloped epithelial indentations. Areas with high grade dysplasia but without invasive carcinoma were demonstrated. This seems to be the first case of serrated adenoma localised in the gastric corpus in the literature.
