This report describes a 43-year-old housewife who suffered a burn and then was suspected of having a sensitivity reaction to Flamazine cream (1 per cent silver sulphadiazine). Patch testing subsequently showed she was sensitive to silver and to cetyl alcohol, but to no other constituents of Flamazine cream. The patient herself knew she was sensitive to silver but was never asked about this possibility, or told initially that Flamazine cream contained silver.
