Fine needle aspiration (FNA) is the modality of choice in the initial characterisation of subcutaneous swellings. The site, distribution, number and clinical association of such swellings determines to a large extent the clinical diagnoses rendered in these cases.
15 unusual cases of subcutaneous cysticercosis, diagnosed by FNA, which clinically simulated diverse aetiologies, are reported.
Three cases occurred in patients with known malignancies which were thought to be metastatic deposits. In another nine cases the clinical diagnoses included lymphoma, squamous cell carcinoma, neurofibroma and lipoma. Two cases strongly mimicked tubercular lymphadenitis, while one case occurred in a renal transplant recipient.
FNA may help diagnosis of a parasitic aetiology in cases where malignancy or tuberculosis is a clinical probability. Cysticercosis should be an integral part of the differential diagnosis of all subcutaneous swellings, regardless of the clinical setting. Helpful cytological clues are discussed.
细针抽吸 (FNA) 是初步描述皮下肿块的首选方法。这些肿块的部位、分布、数量和临床关联在很大程度上决定了这些病例中的临床诊断。
报告了 15 例经 FNA 诊断的不常见皮下囊尾蚴病病例，这些病例在临床上模拟了多种病因。
3 例发生在已知恶性肿瘤患者中，被认为是转移灶。在另外 9 例中，临床诊断包括淋巴瘤、鳞状细胞癌、神经纤维瘤和脂肪瘤。2 例强烈模拟结核性淋巴结炎，1 例发生在肾移植受者中。
在恶性肿瘤或结核病是临床可能性的情况下，FNA 可能有助于诊断寄生虫病因。囊尾蚴病应作为所有皮下肿块的鉴别诊断的一个组成部分，无论临床环境如何。讨论了有帮助的细胞学线索。
