1. adenocarcinoma, moderately differentiated, of colon.
2. the tumor focally involved the entire thickness of muscular layer.
3. the tumor also invaded subserosal layer but did not invoice serosa.
4. presence of lymphovascular invasion.
5. appendix : no pathological alteration.
6. surgical resection ends; proxinal and distal : free of tumor.

2. gall bladder, cholecystectomy :
- chromic cholecystitis, mild.
Macroscopic examination :
1. the specimen consists of a colonic segment measuring 4.5 cm. in length and includes the cecum, vermiform appendix, and a 4 cm. segment of terminal ileum.
Opening specimen reveais fungating ulcerted mass, measuring 1.4 cm. invoiving entire circumference. it situates at 15.5 cm. from colonic end. cut sections reveal whitish gray tissue invading into subserosa. satellite mucosal polyps are not present. mucosal surface of the ileum is unremarkable. representative sections are submitted as a-b = margin, c= appendix, d-h = mass, i-p = lymph nodes
2. the specimen consists of a previously opened gallbladder, measuring 5x3.5x3 cm. the external surface is hyperemic. the wall measures 0.2 up to 0.3 cm thick. the mucosa is poorly velvety. representative sections are taken as Q-R.
