，考虑的太多了，如果病人有钱，可以多做，否则，从前往后排查。
，谢谢！

- Neck 副节瘤 (paraganglioma )FNA and its differential diagnosis (cqz 3)
| 以下是引用天山望月在2008-12-14 13:45:00的发言：
中年，颈部肿块，要可虑原发或转移，不知在颈部何处（正中、侧部）？此例考虑标记： 1、神经内分泌源性:Syn , CgA, S-100 2、肺上皮源性：CK-Pan, CK7, CK8 /18, TTF1, CK20, CK5/6 3、甲状腺的：TTF1, TG, TM 4、涎腺多形性腺瘤：GFAP, PA 5、淋巴造血系统：LCA 6、还要考虑鼻咽部和胃肠道转移。 呵呵 不知当否，请专家点评 |
Above analysis is excellent. We have to think about differential dx first, then decide if IHC study is needed. What IHC will we order if needed. This is way for FNA cytology. We cannot give one dx after we see few photos. Althogh your guess may be right, it is not true interpretation.

This case is difficult and rare. Maybe I should put the case here.
IHC: Chromogranin+, synaptophysin+, GFAP-, EMA-, Pan CK-, calcitonin-
few spindle cells are positive for S-100. Sorry I do not have IHC photos to show you.
Also give you another photo from this case.
Now I hope every one know the dignosis

This is indeed a difficult case. I have to admit that I thought originally that this is going to be a medullary carcinoma of the thyroid. I would do the same immuno stains that Dr. Zhao has done. Now, calcitonin is negative, it pretty much exclude medullary ca. With neuroendocrine markers positive and few cells positive for S-100. I think I know what is the diagnosis. How about our chinese cytopathologists? By the way, I think the arrow in the above photo is pointing to neurosecretory granules, which are best appreciated on DF stain.

谢谢赵博士！
大致翻译如下：
此例是疑难和罕见的。可能是我放到这里原因。
免疫组化：Chromogranin+, synaptophysin+, GFAP-, EMA-, Pan CK-, calcitonin-
少数梭形细胞S - 100 是阳性。很抱歉我没有免疫组化的照片向您展示。
也给你此例的另一张照片。
现在，我希望大家都知道这个诊断。
