The patient was admitted to the hospital due to pulmonary infection, and after anti-inflammatory treatment, peripheral blood eosinophils, C-reactive protein and procalcitonin rised repeatedly. Afterwards, multiple papules and skin crusts appeared throughout the body, and multiple tests were negative for pemphigus vulgaris and bullous pemphigus vulgaris. Scabies mites and eggs were found on the bacterial smear of the skin flakes, which confirmed the diagnosis of Norwegian scabies. After sequential application of 10% sulfur ointment, Jinglian Fukang antibacterial solution (5% permethrin solution) and oral administration of ivermectin tablets, the patient was cured via pathogen confirmation, and the close contacts were also cured after one course of topical application of 10% sulfur ointment.
