I see pathologists in China are not very interested in FNA. Send a cses for discussion.

Older women with a liver mass with a history of intestinal tumor 20 y ago.

FNA of liver mass with DQ and Pap stains

（abin译：我发现国内病理医生对FNA不太感兴趣。上传一例供讨论。病史：老年女性，肝肿块，20年前有肠肿瘤病史。肝肿块FNA标本DQ染色和巴氏染色）

Differential diagnosis鉴别诊断:

 Colon adenocarcinoma结肠腺癌

 Malignant lymphoma恶性淋巴瘤

 Small cell carcinoma小细胞癌

 Malignant Melanoma恶性黑色素瘤

 Breast carcinoma乳腺癌

 Gastric carcinoma胃癌

 Squamous cell carcinoma鳞状细胞癌

 Benign hepatocytes and bile duct epithelium良性肝细胞和胆管上皮细胞

  （天山望月译）

All three got correct dx or interpretation.

1. cell block

2. CD56, somatostatin, glucagon, insulin stains

3.Synaptophysin

4. chromogranin

Previous slides are not available for review. The cytologic features, IHC and history are consistent with metastatic carcinoid.

Few people are interested in FNA cytology or this case is too easy. In fact FNA cytology is the most interesting area. I will show some differential dx.

（abin译：楼上三位的诊断或解释都是对的。

1.细胞块

2.CD56、生长抑素、胰高血糖素和胰岛素染色

3.突触素

4.嗜铬素

无法获得以前的切片供复阅。细胞学特征、IHC和病史均符合转移性类癌。

很少人对FNA细胞学感兴趣或者这一例太简单了？实际上FNA细胞学是最有趣的领域。以后我会提供一些鉴别诊断。）

 谢谢赵老师！如此漂亮的图片！

成簇片状的小圆细胞，可见腺样和菊形团样，小圆细胞核略偏位，核膜厚，染色质粗糙，隐约可见核仁。

结合肠肿瘤病史，考虑神经内分泌癌（类癌）转移。需排除其他小细胞肿瘤。
