Background information: Microtomy artifacts are abnormal structures or features in histological slides resulting from tissue sectioning by microtome. Objective: To determine the type and prevalence of microtomy artifacts found in histopathological tissue sections slides at Bugando Medical Centre (BMC). Methodology: This was a cross-sectional observational study that involved 547 consecutive hematoxylins and eosin (H&E) stained sections of histological archived tissue slides of January 2021. The slides were retrieved from the archives of the histopathology laboratory at BMC, Mwanza Tanzania and analysed for artifacts under a light microscope. Results: A total number of 547 histopathological slides were retrieved for the study and 412 (75.3%) slides had microtomy artifacts present while the remaining 135 (24.7%) histopathological slides had no microtomy artifacts. Of 412 slides with microtomy artifacts, 204(49.5%) slides had only one type of microtomy artifacts while the remaining 208 (50.5%) slides had more than one type of microtomy artifacts. There was a total of 672 microtomy artifacts, and the majority 576 (85.7%) were due to section cutting, followed by trimming artifacts in 92 (13.69%) of the slides. The least artifact was floatation which was seen in 4 (0.6%) of the slides. For the floatation artifact, the folding artifact was the most commonly seen in 300(54.8%) of the slides. Conclusion: Higher prevalence of microtomy artifacts at BMC reflects the problem of interpretation of histopathological slides in our setting. Section folding artifacts were the most prevalent pattern of artifact observed in this study.
