Abstract
OBJECTIVE Procedures for diagnosing bone tumors should be rapid and minimally invasive. Thus, cytological examinations are more useful for such purposes than histological examinations. In order to identify cytomorphological findings that could be used to diagnose bone metastasis from gastrointestinal stromal tumors (GIST), previous cases were reviewed. STUDY DESIGN Cytological samples of 7 lesions from 4 patients with GIST-derived bone metastasis, which were obtained from 2001 to 2017 at the JFCR Cancer Institute Hospital, were reviewed. RESULTS The metastasis of GIST to the bone was clinically suspected before the cytological and histological examinations in all cases since they all involved other metastatic lesion(s), and characteristic osteolytic lesions were detected on radiological images. Although various cell shapes were encountered, spindle cell proliferation was seen in all cytological samples. No pleomorphism was apparent. Characteristic nuclear findings were observed. All of the cases could be diagnosed as GIST-derived bone metastasis. CONCLUSION GIST-derived bone metastasis can be diagnosed by examining cytological samples.

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.
