The cytopathology of benign and malignant breast lesions is described and correlated with the histopathology. Problems in diagnosis and the advantages of fine-needle aspiration are discussed. The diagnostic accuracy is approximately 93% with this technique.

症例は77歳，女性。3か月前からの全身倦怠感と食思不振を主訴に，当院を受診した。造影CT検査で胆嚢腫瘍と肝臓内に多発する腫瘍を認め，入院とした。診断と治療方針決定のため，入院2日目に胆嚢腫瘍に対して超音波内視鏡下穿刺吸引法（Endoscopic ultrasound-guided fine-needle aspiration。以下，EUS-FNA）を施行したところ，その病理診断結果は低分化型腺癌であった。全身化学療法を検討していたが，病理診断を待つ間に食思不振が徐々に悪化し，積極的な治療は希望されずBest Supportive Careの方針となった。EUS-FNAから15日後に自宅退院となり，EUS-FNAから31日後に永眠された。本症例では化学療法につなげることができなかったが，胆嚢病変に対するEUS-FNAは病理組織学的検査において有用な方法と考えられた。

Aims It is still unclear whether endoscopic ultrasound (EUS) contrast-enhanced Harmonic fine-needle aspiration (CH-EUS-FNA) determines superior results in comparison to standard EUS-FNA in tissue acquisition of pancreatic masses. The aim was to compare the pooled diagnostic performances of these two techniques.

EUS is one of the most important tools in the staging of pancreatic tumours and with the linear-array instruments FNA can be performed if malignancy is suspected. We prospectively investigated the diagnostic accuracy of the EUS FNA in our series.

Purpose: Endoscopic ultrasound guided fine needle aspiration (EUS-FNA) is a potential method to diagnose pancreatic mass, but factors associated with the accurate cytological result of EUS-FNA in pancreatic solid tumor are not well known. The aim of this study was to evaluate the yield of EUS-FNA and clinical factors which might have influence on the accuracy of the result of EUS-FNA, such as physicians, location of mass, the number of needle passage attempts and size of mass.

Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is a standard procedure for precise histological diagnosis of pancreas tumors, but it is sometimes difficult to obtain adequate specimens. EUS Sonopsy CY® is a newly designed needle with original features. This randomized study will compare the tissue collection rate of EUS Sonopsy CY® to that of a conventional needle in EUS-FNA. The major eligibility criteria are as follows: Patients with a pancreatic mass referred for EUSFNA; age 20 years, and performance status＜4. The primary outcome is the tissue collection rate. This study will elucidate the efficacy of EUS Sonopsy CY®.
