×参考诊断
考虑肺转移性小细胞癌
引用 6 楼 mjma 在 2011-08-13 11:44:21 的发言:
Based on histology and immunohistochemistry, metastatic neuroendocrine carcinoma needs to be ruled out. I suggest TTF-1 stain. Also pay attention to nuclear morphology at high power view and see if it fits small cell carcinoma. It doesn't have to be a primary CNS tumor just because the border appears infiltrative.
谢谢Dr.mjma和楼上各位的指导。形态学符合小细胞癌。我们加做TTF-1，CD56和NSE，下周有结果。
