COSTA, Juliana Bastos et al. Norwegian scabies mimicking rupioid psoriasis. An. Bras. Dermatol. [online]. 2012, vol.87, n.6, pp.910-913. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962012000600016.
Norwegian scabies is a highly contagious skin infestation caused by an ectoparasite, Scarcoptes scabiei var. Hominis, which mainly affects immunosuppressed individuals. Clinically, it may simulate various dermatoses such as psoriasis, Darier's disease, seborrheic dermatitis, among others. This is a case report of a 33-year-old woman, immunocompetent, diagnosed with generalized anxiety disorder (cancer phobia), who had erythematous, well-defined plaques, covered with rupioid crusts, on her neck, axillary folds, breast, periumbilical region, groin area, besides upper back and elbows, mimicking an extremely rare variant of psoriasis, denominated rupioid psoriasis.
