Delusional infestation (DI) is a psychiatric disorder characterized by a fixed, false belief that the patient is infested with extracorporeal agents. It is known by several names, including the more commonly used term 'delusional parasitosis'. The psychiatric disease is responsible for the cutaneous pathology. About 90% of patients with DI seek help from dermatologists, and most reject psychiatric referral. Thus, effective management requires incorporation of psychiatric principles. We report three cases of DI with inanimate materials, and examine 'Morgellons' disease. We believe that patients with unusual presentations of DI are likely to be seen more commonly in the future. These patients appear to be a subgroup of DI, and may be even more difficult to treat than other patients with DI.
妄想性寄生虫病（DI）是一种精神疾病，其特征是患者固执地坚信自己被体外寄生虫所寄生。它有几个名称，包括更常用的术语“妄想性寄生虫病”。该精神疾病会导致皮肤病变。大约 90%的 DI 患者向皮肤科医生寻求帮助，大多数人拒绝转介到精神科。因此，有效的管理需要结合精神科的原则。我们报告了三例与无生命物质有关的 DI 病例，并研究了“莫吉隆斯症”。我们认为，未来可能会更常见地看到 DI 表现不寻常的患者。这些患者似乎是 DI 的一个亚组，可能比其他 DI 患者更难治疗。
