| Summary points: | A 51-year-old woman with an 8-year history of systemic lupus erythematosus was hospitalised with fever, refractory thrombocytopenia, and generalised rash. Initially, the rash had been diagnosed as a psoriasiform dermatitis and was treated with topical corticosteroids, but after 2 weeks of the corticosteroid therapy, the lesions became scaly, lichenified, crusted plaques on her hands, umbilicus, neck, upper back, armpits, inguinal folds, and legs. The authors discuss an uncommon, hyperkeratotic form of Crusted Norwegian scabies. |
