DRUG HYPERSENSITIVITY SYNDROME

Some types of hypersensitivity to drugs are defined either by the generic name of the drug or descriptive terms. They are sometimes assimilated to pseudolymphoma because the causative drugs are often the same, although the eruption lacks clinical and histopathological criteria of pseudolymphoma. It is then suggested to use 'idiosyncratic drug hypersensitivity syndrome' to define this type of drug reaction. As the skin and other organs may be involved, a generic name would help to determine a better definition and a surveillance program.
