Case ReportsLife-threatening facial edema due to pine caterpillar mimicking an allergic event.
Approximately 150 species of Lepidoptera have been described as causing damage to human skin. One of these species is the pine processionary caterpillar, which is responsible for dermatitis, contact urticaria, ocular lesions and rarely respiratory signs and anaphylactic reactions through IgE-mediated or non-IgE-mediated mechanisms. We report a pediatric case of severe orofacial edema mimicking an allergic reaction after ingestion of a pine processionary caterpillar; urgent airway intubation was required. ⋯ Although oral contact with a pine processionary caterpillar in the form of ingestion is rare, it may cause significant local reaction and airway compromise mimicking an allergic event. In this situation, early intubation to maintain airway patency is a life-saving measure.
