谈不到请教,大家共同学习 无限玄机:确实是这样 核特征: 阿克曼中讲:毛玻璃样核,核内假包涵体,核沟,核内微丝 Nikiforov YE等人最新著作中提到:核增大、排列拥挤重叠、轮廓不规则、核沟、假包涵体、毛玻璃样核 Boerner SL等人还提出了:显著的核仁 其实仔细想想:乳头状癌,首先是肿瘤,而肿瘤的特性是不受限制的增殖。其特征性表现之一就是核增大,这是基础,导致了拥挤重叠、导致了层次增多。这也就是我上面提到的“对比”的意义之所在:只有对比,才能知道是不是大了…… 以上文字,来自前辈无数次的教导,还有很多没有体现出来,水平有限,抱歉…… |
听君一席话,胜读十年书!受益匪浅!请结合您的体现谈一下您对本例的诊断意见,最好有诊断依据!
也希望zhangHY网友发表诊断意见!谢谢!

b.Crowded overlapping nuclei (manifesting as 'up and down' nuclei with no polarity)
c.Pale or clear chromatin (up to ground-glass appearance); or prominent nuclear grooving
d.Psammoma bodies (D.Dx.: calcified colloid
Minor criteria for diagnosis of PTC
a. Abortive papillae
b. Predominantly elongated or irregular-shaped follicles
c. Dark-staining colloid
d. Presence of nuclear pseudoinclusions
e. Multinucleated histiocytes in lumens of follicles
STRICT CRITERIA FOR DIAGNOSIS OF PTC
