Grossing of the sinonasal tract is extremely complicated, as the extent of each surgery (composite resection) varies. Therefore, the sampling of each specimen is unique, and consultation with the surgeon and an experienced head and neck pathologist is recommended.

  • 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
  • Submit resection margins
  • Submit samples of tissue from other sites
Features to report
  • Tumor histologic type and pattern
  • Tumor size and location
  • Tumor histologic grade
  • 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, presence of extracapsular spread
