Abstract Drug-induced lupus (DIL) is due to an autoimmune reaction to a drug with an estimated incidence of 15,000 to 30,000 cases every year in the US. Hydralazine is a well-known offender. Antinuclear antibody (ANA) is present in most cases, though four cases of ANA-negative DIL have been reported. In this report, we present another case of ANA-negative DIL secondary to hydralazine.
