*Iatrogenic tattoos are commonly seen in the context of polypectomy scars. Unfortunately, endoscopists are not good at documenting them; a study from 2021 found 67% of the time the location of the tattoo is not documented.<ref name=pmid33025255>{{cite journal |authors=Hershorn O, Park J, Singh H, Clouston K, Vergis A, Helewa RM |title=Predictors and rates of prior endoscopic tattoo localization amongst individuals undergoing elective colorectal resections for benign and malignant lesions |journal=Surg Endosc |volume=35 |issue=10 |pages=5524–5530 |date=October 2021 |pmid=33025255 |doi=10.1007/s00464-020-08048-8 |url=}}</ref> | |||

Should be signed in a non-committal way (e.g. "focal submucosal fibrosis") if no prior pathology is available/specimen is not labelled something like "old polypectomy site". | Should be signed in a non-committal way (e.g. "focal submucosal fibrosis") if no prior pathology is available/specimen is not labelled something like "old polypectomy site". | ||
The location of any intragenic tattoo(s) should be documented in relation to the suspected scar and correlated with clinical information (if available). | |||
