Abstract

BACKGROUND

The definition of tall cell variant of papillary thyroid carcinoma (TCV-PTC) depends on the articles, and the defined cytological findings characteristic of TCV-PTC have not yet been fully analyzed. This study aimed to establish the cytological characteristics of TCV-PTC.

METHODS

We retrospectively analyzed the smears of 19 TCV-PTC and 50 conventional PTC (C-PTC) cases.

RESULTS

Palisaded pattern with the nuclei locating at the base of tall columnar carcinoma cells was seen in 94.7% of TCV-PTCs, and the incidence was significantly higher than that of C-PTCs (P < .0001). The palisaded pattern tended to appear at the periphery of the cell clusters. Isolated tall columnar carcinoma cells were present in 89.5% of TCV-PTCs. The incidence was significantly higher than that of C-PTC (P = .0001). Tombstone appearance was identified in 78.9% of TCV-PTCs, but not in C-PTCs. Spindle-like carcinoma cells with tapering cytoplasmic end appeared in 68.4% and 12.0% of TCV-PTC and C-PTC, respectively (P < .0001). The cytoplasm of TCV-PTC was densely stained and its cell border was distinct. Cytoplasmic elongation toward an outside of the cell clusters was observed in 89.5% of TCV-PTCs.

CONCLUSION

It is the most important to identify the presence of the tall columnar carcinoma cells on the cytological preparations, in order to distinguish TCV-PTC from C-PTC. We propose five cytological findings indicating TCV-PTC, (1) palisaded pattern, (2) tall columnar cells with the heights of at least three times their widths, (3) tombstone appearance, (4) spindle-like carcinoma cells, and (5) cytoplasmic elongation.

摘要

背景

甲状腺乳头状癌高细胞变体(TCV-PTC)的定义因文献而异,且尚未对TCV-PTC所定义的细胞学特征进行全面分析。本研究旨在确立TCV-PTC的细胞学特征。

方法

我们回顾性分析了19例TCV-PTC和50例传统PTC(C-PTC)病例的涂片。

结果

94.7%的TCV-PTC可见细胞核位于高柱状癌细胞底部的栅栏状模式,其发生率显著高于C-PTC(P <.0001)。栅栏状模式倾向于出现在细胞簇的周边。89.5%的TCV-PTC存在孤立的高柱状癌细胞。其发生率显著高于C-PTC(P =.0001)。78.9%的TCV-PTC可见墓碑样外观,但C-PTC未见。分别有68.4%和12.0%的TCV-PTC和C-PTC出现带有逐渐变细的胞质末端的梭形癌细胞(P <.0001)。TCV-PTC的细胞质染色浓密,细胞边界清晰。89.5%的TCV-PTC观察到细胞质向细胞簇外部延伸。

结论

在细胞学制片上识别高柱状癌细胞的存在对于将TCV-PTC与C-PTC区分开来最为重要。我们提出五项提示TCV-PTC的细胞学表现:(1)栅栏状模式;(2)高度至少为宽度三倍的高柱状细胞;(3)墓碑样外观;(4)梭形癌细胞;(5)细胞质延伸。
