title: Delayed allergic reaction to cefonicid.
abstract: We report a case of delayed cutaneous reaction to intramuscular treatment with cefonicid, a second generation cephalosporin. An isolated late skin test response was observed to cefonicid only and not to other beta-lactams. A patch test with cefonicid 1% was positive after 48 and 96 hours.
