Successful Identification of a Neoplastic Tissue Contaminant in Surgical Pathology

Abstract

Abstract Tissue contamination, where extraneous tissue becomes embedded into the paraffin block or fixed onto the slide, is a relatively common quality issue in surgical pathology and can occur at any step between specimen collection by the clinician and slide coverslipping. We report a case of tissue contamination within a paraffin block and describe our subsequent investigation, which was successful in identifying the source of contamination.
