We describe here a case of Norwegian scabies in a patient with Cushing syndrome, the first case in Korea.
He had complained of intermittent mild itching for 5 month.
Physical examinations revealed the characteristic features of Cushing syndrome and hyperkeratotic brownish papules or/and patches were distributed on the dorsa of hands, axillae, groins, interdigital webs, upper part of the chest and around the neck.
We could find numerous burrows and many mites, eggs, lavas and scybala in the affected :sites on direct microscopic examination with 25% KOH.
Significant laboratory findings were as follows:
1. Total eosinophil count: 0
2. 17-hydroxycorticoids in 24 hr. urine: 10.1 mg/900 cc
3. Bone X-ray series: generalized osteoporosis
4. Mantoux test: negative
About 10 days after topical application of 25% benzyl-benzoate lotion combined with 556 sulfur ointment, the skin lesions were cleared.
We suspect that the lack of delayed hypersensitivity might attribute to the development .of Norwegian scabies in this patient.
