Abstract |
Brazil nuts are the
second most frequent
cause of nut allergy
in the United
Kingdom. We report
the case of a 20-year-old
woman with
documented Brazil
nut allergy who
developed widespread
urticaria and mild
dyspnea after
intercourse with her
boyfriend who had
earlier consumed
Brazil nuts. Skin
prick testing with
the boyfriend’s
semen after Brazil
nut consumption
confirmed signifi
ant reactivity
whereas a sample
before nut
consumption was
negative. We believe
this to be the first
case of a sexually
transmitted allergic
reaction.
Key words:
Brazil nut allergy.
Semen. Sexual
transmission.
