Abstract: Scabies is a contact infectious skin disease caused by scabies mites. Norwegian scabies is a special type of scabies, also known as scabies. It is mainly characterized by extensive skin dryness, desquamation, scabs, cracks, etc. As the symptoms are similar to other skin diseases, it is easy to be confused and misdiagnosed, resulting in patients not receiving timely treatment or receiving unnecessary treatment. HIV infection impairs cell-mediated immunity, increases the risk of Norwegian scabies and makes more aggressive, leading to a poor prognosis. In this paper, we retrospectively analyzed the data of a patient with acquired immunodeficiency syndrome infected with Norwegian scabies complicated with sepsis admitted to Chongqing Public Health Medical Treatment Center. This patient was initially misdiagnosed with psoriasis, after symptomatic treatment failed, the Norwegian scabies was clearly diagnosed by skin pathological biopsy, and sepsis was considered combined with auxiliary examination. Suggests that when AIDS patients have extensive skin inflammatory changes, it is necessary to be alert to the possibility of Norwegian scabies, and pathologic examination should be performed as soon as possible to make a clear diagnosis and timely treatment.
