Erosive pustular dermatosis of the scalp successfully treated with oral zinc sulphate

SIR, Erosive pustular dermatosis ofthe scalp was first described by Pye, Peachey & Burton (1979). All their six patients were elderly women who developed chronic, pustular and occasionally eroded lesions ofthe scalp which produced scarring alopecia. Investigations were essentially negative and skin biopsies showed only non-specific changes of atrophy and chronic inflammation. The condition did not respond to antibiotics, but was suppressed by potent topical steroids. We now report a patient with erosive pustular dermatosis ofthe scalp which responded rapidly to treatment with zinc sulphate.
