[目的]探讨原发性鳃裂癌的细针穿刺细胞学(FNAC)诊断要点。[方法]回顾分析经FNAC诊断的2例鳃裂癌病例。[结果]2例鳃裂癌均表现为鳃裂残迹部位的囊实性包块,囊性部分涂片为鳃裂囊肿改变,实质部分涂片可见不同分化阶段的鳞状细胞(从正常表层细胞到低级别病变、高级别病变及鳞癌细胞),可见成团凝固性坏死及角化物,背景中散在或成簇的淋巴细胞,细胞蜡块切片可清晰显示高分化鳞癌图像。[结论]鳃裂癌术前诊断上应与转移性鳞癌、鳃裂囊肿、淋巴结结核鉴别,结合细胞蜡块,FNAC是诊断鳃裂癌的简便有效的方法。
[Objective] To investigate the diagnostic points of fine needle aspiration cytology (FNAC) in primary gill carcinoma. [Methods] Two cases of gill carcinoma diagnosed by FNAC were retrospectively analyzed. [Results] The two cases of gill carcinoma showed cystic solid mass at the site of branchial gills rupture. The cystic part smear was changed as branchial glottic cyst. Sperm cells at different stages of differentiation were observed in the smear. To low-grade lesions, high-grade lesions and squamous cell carcinoma), visible coagulation necrosis and keratosis, background scattered or clustered lymphocytes, cell paraffin section can clearly show well-differentiated squamous cell carcinoma images. [Conclusion] The preoperative diagnosis of branchial gill carcinoma should be differentiated from metastatic squamous cell carcinoma, branchial cleft cyst and lymph node tuberculosis. The combination of cellular wax block and FNAC is a simple and effective method for the diagnosis of branchial.
