Exact data concerning the incidence of cutaneous drug eruptions are lacking due to underreporting. Diagnostics of cutaneous drug eruptions is hampered by the fact that one drug may induce different eruptions while the same cutaneous eruption can be caused by several drugs. Important steps in the diagnostics of cutaneous drug eruptions are: suspicion of the drugs as cause of the eruption, precise history-taking with emphasis on medication use and a complete physical examination. The 'golden standard' in the diagnostics of a drug eruption is the dechallenge-rechallenge procedure, but in severe cutaneous reactions such as Stevens-Johnson syndrome, toxic epidermal necrolysis and vasculitis, this procedure can cause severe, sometimes life-threatening reactions. Reporting suspected adverse drug reactions to pharmacovigilance centres is important to identify rare drug reactions.
