Total parenteral nutrition (TPN) is a commonly used treatment method for patients whose oral intake is insufficient or who cannot use the gastrointestinal system. In the literature hypersensitivity reactions to contents of PN and fats are very rare. But these reactions can be seen in a wide spectrum from minor reactions such as pruritus to life-threating reactions such as anaphylaxis. In this case, a hypersensitivity reaction case will be presented against the trace element product in PN. As far as we know, there are no other cases in the literature that are definitely associated with trace element solution.
