Acute low-dose hydralazine induced lupus syndrome (HILS).

A case of acute hydralazine induced lupus syndrome is described. No case has previously been described in which a small daily dose and a small accumulation dose have evoked this syndrome in such a short period of time. A pertinent and selective review of this syndrome is presented. The need for awareness of this syndrome manifesting in a patient exposed to small doses of hydralazine for short periods of time is emphasized.
