Hie corticosteroids provided initial relief, but the psoriasis recurred once the medication was discontinued. This patient had been in a county jail for about 18 months; during his confinement, he was not exposed to sunlight. Moreover, he was not given emollients and creams. Like most inmates, he had no control over temperature or humidity regulation of his housing unit, which had a tendency to be dry. Also, the choice of medication was subject to a limited drug formulary.
