Beyond determining overall malignancy diagnosis (such as adenocarcinoma), probable origin and staging, classification of tumors into a specific histopathologic type or grade is generally of relatively less value. In cases of clearly non-malignant tumors where it is difficult to determine the specific histopathologic type or grade, it is generally acceptable to conclude the evaluation and report it as such, unless the clinician specifically requests otherwise. For potentially malignant or high-risk tumors, typing and grading often still affects the management.

Additional slices are indicated in the following situations:
Additional material is indicated in the following situations:
*Re-excision does not identify tumor cells in a clearly non-radical primary excision or biopsy.<ref group="notes">In such cases, step slices are taken rather than serial ones.</ref>
*Re-excision does not identify tumor cells in a clearly non-radical primary excision or biopsy.
*The most aggressive pattern is seen in the last available section, in which case more sections are indicated (from the same paraffin block if additional tissue is not available).
*The most aggressive pattern is seen in the last available section, in which case more sections are indicated (from the same paraffin block if additional tissue is not available).
Depending on availability and greatest suspicion, additional material is either acquired by taking addition step sections of remaining tissue in a paraffin block, or taking additional slices from the original specimen.
