mites are common ectoparasites of the human pilosebaceous units. Most adults are infested with mites without clinical symptoms. mite will only become a pathogenic organism when there is an abnormal increase in the number of mite density. This situation happens when the equilibrium between mites, skin microenvironment and human immunity system changes. infestation can cause multiple skin disorders, which are grouped under the term demodicosis or demodicidosis. Clinical manifestations of demodicosis can mimic other known skin diseases such as folliculitis, rosacea, perioral dermatitis, which is why it is often misdiagnosed. Diagnosis criteria consists of relevant correlation of suspected clinical skin lesions, confirmed by the presence of abnormal proliferation of mites and by clinical cure after acaricidal treatment together with normalization of mite density. Dermatologists should be aware that demodicosis is not an uncommon skin disease, and there are still many unknowns about it that should be researched further.
螨虫是人体毛囊皮脂腺单位常见的体表寄生虫。大多数成年人感染螨虫但无临床症状。只有当螨虫密度异常增加时，螨虫才会成为致病生物。当螨虫、皮肤微环境和人体免疫系统之间的平衡发生变化时，就会出现这种情况。螨虫感染可导致多种皮肤疾病，这些疾病统称为蠕形螨病。蠕形螨病的临床表现可模仿其他已知的皮肤病，如毛囊炎、酒渣鼻、口周皮炎，这就是它经常被误诊的原因。诊断标准包括疑似临床皮肤病变的相关关联，通过螨虫异常增殖的存在以及杀螨治疗后临床治愈且螨虫密度恢复正常来确诊。皮肤科医生应意识到蠕形螨病并非罕见的皮肤病，关于它仍有许多未知之处有待进一步研究。
