Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
BACKGROUND. Well-differentiated hepatocellular carcinoma (HCC) in fine-needle aspiration (FNA) biopsy is characterized by trabeculae three or more cells thick wrapped by peripheral endothelium. The authors encountered another pattern that did not fulfill these classic criteria for malignancy yet was proven to be HCC in clinical follow-up. The objective of this study was to characterize the cytologic features of this pattern with histologic correlations. METHODS. Over a period of 6.5 years, 14 of 123 cases (11.4%) of HCC from 428 liver aspirates showed the unusual pattern. Their cytologic features were compared with 14 cases of nonneoplastic liver on FNA smears that were processed with Ultrafast Papanicolaou stain, and their histologic features were compared on cell blocks with hematoxylin and eosin stain and reticulin stain. RESULTS. The unusual type of well differentiated HCC in FNA smears was characterized by numerous, small hepatocytes with minimal nuclear atypia but reduced cytoplasm, grouped together in microacini of five or more cells and microtrabeculae one or more cells thick of irregular thickness with no apparent peripheral endothelium. Transgressing capillaries were found when the smears were inspected carefully. In histology nine cases that were the compact type of HCC, two cases that were the microacinar type of HCC, and three cases that were the microtrabecular type of HCC. All FNAs showed deficient reticulin framework. All 14 cases of nonneoplastic liver aspirate were characterized by the presence of large tissue fragments that were resistant to smearing. CONCLUSIONS. Well differentiated HCC may present as microtrabeculae of irregular thickness one or more cells thick with inapparent peripheral endothelium or as microacini mimicking neuroendocrine carcinoma. © 2003 American Cancer Society.
