BACKGROUND
Delusional parasitosis is a rare, fixed, false belief that an individual is infested with parasites or other living organisms despite no laboratory evidence to confirm this belief. It can manifest as a shared belief, folie à deux, or by proxy.
CASE PRESENTATION
This case report describes an 8-year-old patient with Trisomy 21 with delusional parasitosis by proxy. The patient's mother remained fixated on the patient having a parasitic infection despite extensive reassuring evaluations. There were multiple normal-appearing pictures and videos of the patient's urine, stool, skin and throat shown to the medical team, consistent with the "specimen sign" described in the literature.
CONCLUSIONS
Delusional parasitosis is rare and can be difficult to diagnose and treat. It has even more complexity and implications in pediatric or other vulnerable populations. A multidisciplinary treatment approach is important to build trust and prevent harm.
背景
妄想性寄生虫病是一种罕见的、顽固的、错误的信念，即尽管没有实验室证据证实，但个体坚信自己感染了寄生虫或其他生物体。它可表现为共享性信念、感应性精神病或代理型。
病例介绍
本病例报告描述了一名患有21三体综合征的8岁患者，患有代理型妄想性寄生虫病。尽管进行了广泛的安抚性评估，但患者的母亲仍坚信患者患有寄生虫感染。向医疗团队展示了患者尿液、粪便、皮肤和喉咙的多张外观正常的图片和视频，这与文献中描述的“标本体征”一致。
结论
妄想性寄生虫病很罕见，诊断和治疗可能很困难。在儿科或其他弱势群体中，其情况更为复杂且影响更大。多学科治疗方法对于建立信任和防止伤害很重要。
