50 years old woman was referred due to an EGC. Initial biopsy was "TUBULAR ADENOCARCINOMA, POORLY DIFFERENTIATED, with lymphoid stroma", but the patient strongly wanted non-surgical treatment. ESD was done.
ESD: Early gastric carcinoma
1. Location : high body, lesser curvature
2. Gross type : EGC type IIb+IIc
3. Histologic type : tubular adenocarcinoma, moderately differentiated with lymphoid stroma (suspicious for carcinoma with lymphoid stroma)
4. Histologic type by Lauren : intestinal
5. Size of carcinoma : (1) longest diameter, 10 mm (2) vertical diameter, 9 mm
6. Depth of invasion : invades mucosa (lamina propria) (pT1a)
7. Resection margin : free from carcinoma(N), safety margin : distal 13 mm, proximal 8 mm, anterior 16 mm, posterior 12 mm, deep 50 ㎛
8. Lymphatic invasion : not identified(N)
9. Venous invasion : not identified(N)
10. Perineural invasion : not identified(N)
11. Microscopic ulcer : absent
12. Histologic heterogeneity: absent
Pre-ESD biopsy was undifferentiated type, and the post-ESD pathology was differentiated type.
