, known as bird mite, generally lives on nestlings' featherless skin. Humans are accidentally infected, and itchy dermatitis is induced when the mites are unable to use birds' blood. The diagnosis is difficult due to the very small size and rapid movement of the mites, which make them hard to spot.
A 14-year-old male and his mother were referred to the allergy clinic complaining of a 2-week generalized itchy cutaneous papular lesion, unresponsive to antihista-mines, with the feeling of an insect moving on the surface of the skin. Due to the history of recently hatched pigeons nesting on their balcony and finding very small bugs, diagnosed as , they were instructed to clean the pigeon's nest as the source of these parasites, which successfully solved the problem.
Bird mite infestation should be considered in the differential diagnosis of recurrent pruritus and urticaria, refractory to conventional treatments. Physicians should be aware of this mite infestation in approach to any patient with papular urticaria.
鸟螨，又称禽螨，通常寄生在雏鸟的无毛皮肤上。人类偶然感染，当螨虫无法吸食鸟类血液时，就会引发瘙痒性皮炎。由于螨虫体积非常小且移动迅速，难以发现，因此诊断较为困难。
一名 14 岁男性和他的母亲因全身瘙痒性丘疹性皮疹 2 周就诊于过敏诊所，抗组胺治疗无效，自觉有昆虫在皮肤表面活动。由于最近在阳台上有鸽子筑巢，且发现了非常小的虫子，诊断为鸟螨，他们被指示清理鸽子窝作为这些寄生虫的源头，成功地解决了问题。
对于反复发作的瘙痒和荨麻疹，常规治疗无效时，应考虑鸟螨感染的鉴别诊断。对于任何出现荨麻疹的患者，医生都应意识到这种螨虫感染的可能性。
