Background/Aim: To investigate the clinicopathological characteristics of high-grade squamous intraepithelial lesions (HSILs) and squamous cell carcinomas (SCCs) involving endocervical polyps (ECPs). Patients and Methods: We collected the endocervical polypectomy cases and performed pathological examination and cytohistological correlation. Results: During a period of 12 years, 21 (1.1%) HSILs and two (0.1%) SCCs involving ECPs were identified in 1,905 cases. Twelve (63.1%) of the 19 cases were cytohistologically concordant. In five HSILs and one SCC with polypectomy margin involvement, residual HSIL was identified in conization or hysterectomy specimens. Furthermore, in two HSIL patients and one SCC patient with negative polypectomy margins, residual HSILs were found in the conization specimens. Conclusion: The prevalence of HSIL and SCC involving ECP in our cohort was similar to the rates found in previous studies. The presence of residual HSIL in nonpolypoid cervical tissue regardless of the polypectomy margin involvement suggests that conization or hysterectomy is needed for diagnostic or treatment purposes.

涉及宫颈息肉的鳞状细胞癌和高级别鳞状上皮内病变的临床病理特征

背景/目的：研究涉及宫颈息肉（ECP）的高级别鳞状上皮内病变（HSIL）和鳞状细胞癌（SCC）的临床病理特征。患者和方法：我们收集宫颈息肉切除术病例并进行病理检查和细胞组织学相关性。结果：在 12 年的时间里，在 1,905 例病例中发现了 21 (1.1%) 个 HSIL 和两个 (0.1%) 涉及 ECP 的 SCC。19 例中有 12 例 (63.1%) 在细胞组织学上是一致的。在 5 个 HSIL 和 1 个有息肉切除边缘受累的 SCC 中，在锥切或子宫切除标本中发现了残留的 HSIL。此外，在两名 HSIL 患者和一名具有阴性息肉切除边缘的 SCC 患者中，在锥切标本中发现了残留的 HSIL。结论：我们队列中涉及 ECP 的 HSIL 和 SCC 的患病率与先前研究中发现的比率相似。无论息肉切缘是否受累，非息肉状宫颈组织中残留 HSIL 的存在表明需要锥切术或子宫切除术以进行诊断或治疗。
