An unusual case of food protein-induced enterocolitis syndrome due to zucchini.

BACKGROUND

Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-mediated food allergy characterized by gastrointestinal symptoms, mainly protracted and delayed vomiting. Diagnosis is based on clinical history, and it can be challenging as symptoms are delayed and the causative food is often not very suspicious.

OBJECTIVE

This case report highlights the importance of having a high degree of suspicion to reach a correct diagnosis.

MATERIALS AND

METHODS

We report an unusual case of FPIES due to zucchini. During the follow-up. Two oral food challenges (OFC) were carried out to evaluate tolerance to the food involved.

RESULTS

The first OFC was positive and in the second the child tolerated the food without problems.

CONCLUSIONS

In this case, the OFC was essential to identify the offending food and to verify that the child had overcome the disease.
