BACKGROUND
There are only very few reports of cervical toxoplasma lymphadenitis being diagnosed exclusively via fine-needle aspiration cytology (with serology).
CASE REPORT
We describe a case of toxoplasma lymphadenitis that was successfully diagnosed by fine-needle aspiration cytology. The case involved a male patient who was immunocompromised as a result of recurrent acute myelogenous leukaemia with cervical lymphadenopathy. The biopsy showed typical features of a well-defined pseudocyst containing Toxoplasma gondii tachyzoites.
CONCLUSION
Toxoplasma lymphadenitis is a common cause of lymph node enlargement. Fine-needle aspiration cytology is a useful method for diagnosing and differentiating toxoplasma lymphadenitis from more serious causes of lymphadenopathy, such as metastatic lymphadenopathy or lymphoma.
背景
仅有极少数关于单纯通过细针穿刺细胞学检查（结合血清学）诊断宫颈弓形虫淋巴结炎的报道。
病例报告
我们描述了一例通过细针穿刺细胞学检查成功诊断的弓形虫淋巴结炎病例。该病例为一名男性患者，因复发性急性髓系白血病导致免疫功能低下，并伴有颈部淋巴结病。活检显示出典型特征，即有一个界限清晰的假囊肿，内含刚地弓形虫速殖子。
结论
弓形虫淋巴结炎是淋巴结肿大的常见原因。细针穿刺细胞学检查是诊断弓形虫淋巴结炎并将其与更严重的淋巴结病病因（如转移性淋巴结病或淋巴瘤）相鉴别的有用方法。
