Cysticercosis is more common than usually thought. Fine needle aspiration cytology (FNAC) plays an important role in prompt recognition of this disease.
To study the role of FNAC in the diagnosis of cysticercosis.
Twenty-two patients with subcutaneous and intramuscular nodules, who were clinically diagnosed as tuberculous lymphadenitis, reactive lymphadenitis, lipoma, neurofibroma and cysticercosis were included in the present study.
In nine cases, a definitive diagnosis of cysticercosis was obtained in the form of fragments of parasite bladder wall and, biopsy confirmed the diagnosis. In the rest 13 cases, larval fragments could not be identified on the aspirates and the diagnosis of parasitic inflammation was suggested on the basis of other cytomorphological findings. Follow-up biopsy confirmed the diagnosis of cysticercosis.
FNAC in cysticercosis is a low-cost outpatient procedure. The cytological diagnosis is quite straightforward in cases where the actual parasite structure is identified in the smears. However, in other cases, presence of eosinophils, histiocytes which may be in palisaded clusters or not, a typical granular dirty background, etc., are the features which should always alert the pathologist to this possibility.
囊尾蚴病比通常认为的更为常见。细针穿刺细胞学检查（FNAC）在该病的早期识别中发挥着重要作用。
研究FNAC在囊尾蚴病诊断中的作用。
本研究纳入了22例皮下和肌内结节患者，这些患者临床诊断为结核性淋巴结炎、反应性淋巴结炎、脂肪瘤、神经纤维瘤和囊尾蚴病。
9例患者通过寄生虫囊壁碎片确诊为囊尾蚴病，活检证实了诊断。其余13例患者的吸出物中未发现幼虫碎片，根据其他细胞形态学发现提示为寄生虫性炎症。随访活检证实为囊尾蚴病。
囊尾蚴病的FNAC是一种低成本的门诊检查方法。在涂片上识别出实际寄生虫结构的病例中，细胞学诊断相当直接。然而，在其他病例中，嗜酸性粒细胞、可能呈栅栏状聚集或不呈栅栏状聚集的组织细胞、典型的颗粒状污秽背景等特征，应始终提醒病理学家注意这种可能性。
