TOWERSEY, Loan et al. Dermoscopy of Norwegian scabies in a patient with acquired immunodeficiency syndrome. An. Bras. Dermatol. [online]. 2010, vol.85, n.2, pp.221-223. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962010000200013.
The authors report here on the case of a female patient with Norwegian (crusted) scabies and acquired immunodeficiency syndrome whose compliance with antiretroviral therapy was poor. Definitive diagnosis was confirmed by direct microscopic examination, which revealed numerous Sarcoptes scabei. Dermoscopy showed pathognomonic scabetic burrows and brownish structures in the shape of a hand-glider with a millipede-like appearance. The latter constitutes a diagnostic feature in the pathology of Norwegian scabies that has not yet been described. The patient responded well to oral ivermectin and topical vaseline with sulphur at a proportion of 10%. There was a simultaneous improvement in dermoscopic parameters.
