"The gastric serrated adenoma has elongated fronds with lateral crenated, saw tooth-like notches as a result of scalloped epithelial indentations. The serrated crypts are lined by overtly dysplastic epithelial cells containing abundant eosinophilic cytoplasm and stratified elongated penicillate nuclei. These microscopic features mimic traditional serrated adenoma found in the colorectum." º´¸®ÇÐÀûÀ¸·Î Åé´Ï¸ð¾çÀ» º¸ÀÌ´Â °ÍÀÌ°í ÀÓ»óÀû Ư¼º¿¡ ´ëÇÑ ±Ô¸íÀº Á» ´õ ±â´Ù·Á¾ß ÇÒ µíÇÕ´Ï´Ù.

[2018-8-25. Ãß°¡] Small gastric cancer can have deep SM invasion.
ESD : Early gastric carcinoma
1. Location : high body, posterior wall
2. Gross type : EGC type IIc
3. Histologic type : tubular adenocarcinoma, moderately differentiated with serrated feature
4. Histologic type by Lauren : intestinal
5. Size of carcinoma : (1) longest diameter, 6 mm (2) vertical diameter, 6 mm
6. Depth of invasion : invades submucosa, (depth of sm invasion : 1200 §) (pT1b)
7. Resection margin : involved deep resection margin by carcinoma with cauterized artifact negative other resection margins; safety margin : distal 3 mm, proximal 2 mm, anterior 16 mm, posterior 4 mm, deep 0 §
8. Lymphatic invasion : not identified(N)
9. Venous invasion : not identified(N)
10. Perineural invasion : not identified(N)
11. Pre-existing adenoma : none
12. Microscopic ulcer : absent
13. Histologic heterogeneity: absent
Becuase of the deep SM invasion and positive vertical margin, additional surgical treatment was recommended.
The meaning of the serrated feature in the gastric neoplasm is still unclear.
