title: Drug-induced chronic pigmented purpura.
abstract: A close correlation between purpuric reaction and drugs was observed in seven cases of chronic pigmented purpura. The patients developed purpuric lesions after taking certain drugs for more than 3 years, were thiamine propyldisulfide in 2 cases, and chlordiazepoxide in 1 case. The purpuric lesions stopped recurring after removal of the drugs in the rest of the cases. It is suggested that drugs are among the etiological factors in chronic pigmented purpura.
