Pathology-narrative de-identification is the removal of patient and accession IDs from the free-text part of a report. It meets HIPAA Safe Harbor (45 CFR §164.514(b)). anonym.plus runs locally and keeps the gross, micro, and diagnosis text whole.
When this applies
These reports drive tumor registries and teaching sets. But each one carries the name, accession number, and sending doctor. Strip those before you share it.
How anonym.plus handles it
- Load the report into anonym.plus on your device.
- It finds the name, accession or case number, and sender.
- The gross, micro, and diagnosis text stays in place.
- Swap IDs with steady labels across linked specimens.
- Save the clean report on your device.
What you need to provide
- The report (PDF, DOCX, or LIS export).
- An operator (Replace works well for registries).
- Optional accession map to keep one case's parts linked.

Limitations & cautions
A rare tumor type plus a collection date and a small catchment area can re-identify, even after IDs go. For uncommon cases, make dates broad and use Expert Determination rather than Safe Harbor alone.
Frequently asked questions
Does the swap touch the diagnosis text?
No. The gross, micro, and final diagnosis stay. Only IDs like name and accession number change.
Can the parts of one case stay linked?
Yes. An accession map keeps all parts of one case under a single label.
Is the LIS export supported as well as the PDF?
Yes. The narrative PDF or DOCX and the structured LIS export both work.
