ABSTRACT
In histology, the correct handling and orientation of small/thin biopsies is often crucial for diagnosis. Automation is progressively growing and modifying the routine work in the histopathology laboratories, providing new chances for quality improvement and workload optimization. We have tested the use of Paraform orientation gels together with an automated embedding system for processing small/thin biopsies, first skin, but also other tissue/organ biopsies. The study aimed to assess the benefits and challenges of routinely using orientation gels in a high throughput pathology laboratory. Gel introduction required a short training of the pathologists, including trainees, at grossing; it did not cause significant delay at grossing, interference with embedding, or microtome steps, whereas re-do inclusions and re-cut slides were significantly reduced. In conclusion, orientation gel and automatic embedding constituted an efficient system for small/thin biopsies that had to be correctly placed and orientated, allowing the re-modeling of technicians' workflow and very safe handling of small/thin biopsies that were not manipulated further after grossing.
