Crusted scabies is a severe variant of scabies caused by the ectoparasite Sarcoptes scabiei. It is characterized by high mite burden, extensive hyperkeratotic scaling, crusted lesions, variable pruritus, generalized lymphadenopathy, erythroderma, and eosinophilia, in some cases. There is an increased incidence of crusted scabies, particularly among patients with HIV infection. We describe a 22-year-old Syrian immunocompetent female who had hyperkeratotic psoriasiform plaques and hyperkeratosis without itching. She was treated with oral albendazole and topical crotamiton with salicylic acid 5 percent.
结痂性疥疮是由体外寄生虫疥螨引起的一种严重的疥疮变体。其特征为螨虫负荷高、广泛的角化过度性鳞屑、结痂性损害、不同程度的瘙痒、全身性淋巴结病、红皮病,在某些情况下还有嗜酸性粒细胞增多。结痂性疥疮的发病率有所增加,尤其是在艾滋病毒感染患者中。我们描述了一名22岁免疫功能正常的叙利亚女性,她有角化过度的银屑病样斑块和角化过度但无瘙痒症状。她接受了口服阿苯达唑和外用含5%水杨酸的克罗米通治疗。
