RESUMO
The patient was a 3-year-old girl whose father was employed sorting and washing soybeans. She exhibited transient respiratory distress and loss of activity on the same day or the next day after her father came home wearing work clothes with soybean dust on them. One day, she developed anaphylaxis after being lifted into her father's arms while he was wearing his work clothes. Although a blood test was positive for soybean and Gly m 4-specific IgE antibodies, the girl was able to consume soy products (not including soy milk, which she had never consumed) without any issues. The father was instructed to change clothes before leaving work and bathe immediately upon returning home, and the girl has not had any further episodes of respiratory distress, loss of activity, or anaphylaxis. Though reports of anaphylaxis from soybean antigen inhalation are extremely rare, it is very likely that inhalation of soybean dust from the father's work clothes induced anaphylaxis in this case.
