镰刀菌,一种常见且高度传染性的皮肤感染,是由螨虫Sarcoptesscabieivar引起的.hominis.识别患有sc疮的人通常会带来诊断挑战,因为它的临床特征类似于其他皮肤病,如药物反应,特应性皮炎,和接触性皮炎。此外,皮肤表现来自对螨虫及其副产品的延迟型免疫反应,允许一些人携带螨而不出现症状。有明显的传染性,以及无症状携带者的可能性,为同居者创造了多重治疗障碍,因为不治疗所有密切接触者可能会导致再次感染。本报告介绍了一名46岁的越南男性,他患有严重的红斑,鳞状,还有四个月的瘙痒性皮疹.尽管三个不同的皮肤科医生开了外用皮质类固醇的处方,他的皮疹持续。经过全面评估,被诊断为脓肿。该患者接受了杀菌剂治疗,最初缓解了他的症状;然而,三周后,他的症状又出现了.进一步调查显示,他的妻子是无症状的携带者,没有接受治疗。这个病例突出了临床特征,发病机制,和治疗方案,同时强调及时识别和治疗所有密切接触者的重要性。
Scabies, a common and highly contagious skin infestation, is caused by the mite Sarcoptes scabiei var. hominis. Identifying individuals with
scabies often poses a diagnostic challenge, as its clinical features resemble other dermatologic conditions such as drug reactions, atopic dermatitis, and contact dermatitis. Furthermore, the cutaneous manifestations arise from delayed-type immunologic reactions to the mites and their byproducts, allowing some individuals to carry the mite without showing symptoms. The significant transmissibility of scabies, along with the potential for asymptomatic carriers, creates multiple treatment hurdles for cohabiting individuals, as the failure to treat all close contacts can result in re-infestation. This report presents the
case of a 46-year-old Vietnamese male who suffered from a worsening erythematous, scaly, and pruritic rash for four months. Despite being prescribed topical corticosteroids by three different dermatologists, his rash persisted. Upon thorough evaluation,
scabies was diagnosed. The patient was treated with scabicidal agents, which initially alleviated his symptoms; however, three weeks later, his symptoms resurfaced. Further investigation revealed that his wife was an asymptomatic carrier who had not received treatment. This
case highlights the clinical features, pathogenesis, and treatment options for
scabies while emphasizing the importance of promptly identifying and treating all close contacts.
