A 3-month-old male infant presented with a skin rash affecting his limbs since the age of 1 month. He was treated with topical steroids by his pediatrician； however, he did not improve. He visited our hospital with his mother because his father was diagnosed with scabies at our hospital. Examination showed red papules scattered on his face, trunk, and limbs.
