Grossing
- Ink pancreatic duct and common bile duct margins, also retroperitoneal margin
- Probe common bile duct and pancreatic duct, and section along plane of both probes
- Should examine at least 12 lymph nodes in a pancreaticoduodenectomy specimen
Features to report - small intestine
- Tumor location
- Histologic type
- Histologic grade if relevant (well differentiated: > 95% glands; moderately: 50 - 95% glands; poorly: 5 - 49% glands; undifferentiated: < 5% glands)
- Tumor size
- Extent / depth of invasion
- Margin involvement (proximal, distal, radial [soft tissue closest to deepest tumor penetration]) and distance of tumor to margin
- Invasion of other structures
- Obstruction, perforation, ulceration, proximal dilation
- Nuclear grade, presence of necrosis
- Angiolymphatic invasion
- Other pathologic findings (polyps, Crohn's disease, celiac disease)
- Nodal involvement (number involved, number identified)
- Results of special studies
Features to report - ampulla
- Specimen type
- Tumor site
- Presumed tumor origin (intraampullary, periampullary duodenum, mixed, common bile duct, pancreatic)
- Histologic type
- Histologic grade (well, moderate, poor or undifferentiated)
- Tumor size (invasive carcinoma component)
- Depth of invasion, local extension
- Margins - invasive carcinoma; distance to closest margin and identify margin (recommended to ink posterior retroperitoneal surface of pancreas and submit sections of tumor closest to this margin)
- Margins - carcinoma in situ; involvement of pancreatic duct or common bile duct margin
- Margins - PanIn
- Pathologic staging
- Perineural invasion (for resections)
- Angiolymphatic invasion (for resections)
- Lymph nodes
- Additional findings: PanIN / dysplasia, adenoma, inflammation, adenomyosis, pancreatitis, gastritis, other
