The hidden scabies: a rare case of atypical Norwegian scabies, case report and literature review

Abstract

Abstract Background Norwegian scabies is a rare dermatological manifestation that usually affects the most fragile populations, such as elderly and immunocompromised patients, and its diagnosis is quite complex, due to its low prevalence in the general population and because of a broad spectrum manifestation. Case Presentation Here we describe a rare case of Norwegian scabies that was previously misdiagnosed in a sixteen year old patient affected by Down syndrome and we conducted a non-systematic literature review about this topic. Lesions were atypical, pruritic and associated with periodic desquamation of the palms and soles and after a series of specialist evaluations, she finally underwent topical treatment with complete remission. Conclusion It is therefore crucial to take in consideration the relation between Down syndrome and community acquired crusted scabies, to enable preventative measures, early detection, and proper treatment.
