Paper abstract bibtex The backbone of daily pathological diagnostic work is the paraffin section. Paraffin sections are still prepared by methods largely unchanged for over 150 years. A xylene-free method has been developed that excludes xylene, not only as the intermediate step before the paraffin baths, but also for deparaffinizing of the cut sections, which also eliminates the need for rehydration and dehydration for the staining and mounting steps. Elimination of xylene from tissue processing cuts costs, saves time, and improves the laboratory environment. Experience with xylene-free sections since 1995 at the Vrinnevi Hospital is favorable. Our opinion is that the xylene-free sections are equivalent to conventionally processed sections. To test this hypothesis, nine pathologists from three hospitals participated in an evaluation trial. Paired tissue blocks from 10 consecutively submitted samples each of breast, intestine, and skin were processed by either the xylene-free or the conventional method. Sections from each block were deparaffinized and stained with hematoxylin-eosin (H&E), with periodic acid-Schiff (PAS), and with van Gieson's method. A randomized mix of 180 sections (10 samples x 3 tissues x 3 stains x 2) gave 90 matched pairs. Each section was blindly examined and scored by nine pathologists to give 810 paired observations for statistical evaluation. The xylene-free sections were ranked as good as or better than their conventional counterparts in 74% of the comparisons, and poorer in 26%. The major discriminating factor was the staining method. H&E and PAS sections were equivalent. The xylene-free van Gieson sections, cut from the same blocks and randomly assigned to this stain, tended to be downgraded. This could be traced to a faulty stain solution used for this batch. The overall results have demonstrated professional acceptance for the xylene-free method of processing histological sections.
