Abstract:
The cytological diagnosis of hepatocellular adenoma (HCA) is difficult since it is a very rare tumor and lacks characteristic cytological features. We have just reported a case of inflammatory HCA that displayed an unusual histological pattern (Clin J Gastroenterol 8:426–434, 2015). A touch cytology smear sample was obtained from the surgical specimen, and it also exhibited very unique features. A 56‐year‐old male underwent partial hepatectomy for an inflammatory HCA (diameter: 1.4 cm) in the right posterior lobe of the liver. The cytological sample displayed a characteristic two‐cell pattern. One type of cells contained thick cytoplasm, a high nucleus/cytoplasmic ( N / C ) ratio, and well‐defined cytoplasmic borders. The other type demonstrated small pyknotic nuclei and a lower N / C ratio. The immunohistochemical staining pattern of the histological specimen suggested that the latter cells might have been undergoing apoptosis. We report a case of inflammatory HCA with characteristic features. To diagnose this type of variant, it is important to recognize the unique pattern described in this study. Diagn.
