[Kidney lesion from phenacetin]

After a short survey of the most important toxical lesions of the human organism by phenacetin a report is given on a 65-year-old female patient. An abuse of phenacetin lasting 20 years (calculated total quantity: more than 1 kg) led to a lesion of the kidney and rejection of the papilla. The anamnesis confirms the frequently thoughtless prescription of phenacetin-containing medicaments and emphasizes their sequelae. By a clarifying talk with the appreciative patient the abuse of phenacetin could be finished.
