Grossing
- At least one section per 1 cm of tumor for large tumors, including tumor center and periphery
- Submit entire tumor if can do so in 5 sections or less
- Resection margins
- Save intervening levels on biopsies for special stains
Features to Report
- Tumor histologic type and pattern
- Tumor size and location
- Tumor histologic grade
- Depth of invasion (not used for TNM staging)
- Pattern of invasion (noncohesive irregular cords, infiltrative single cells, well defined blunt pushing borders, thick rounded invasive cords)
- Tumor extension to adjacent structures
- Status of resection margins
- Vascular invasion
- Perineural invasion
- Lymph nodes: for each level, number obtained, number involved by tumor, size of nodal metastases and presence of extracapsular spread
- Dysplasia
- References: Mod Pathol 2000;13:1038
Measurements
- Endophytic tumors: measure perpendicularly from surface of invasive carcinoma to deepest area of involvement, using nontangential sections with a clearly recognizable surface component
- Exophytic tumors: measure tumor thickness from surface to deepest area
- Ulcerated tumors: measure from ulcer base to deepest area as well as from surface of most lateral extent of invasive carcinoma to deepest area
