RESUMO
In this retrospective series of 97 cases of manchineel fruit ingestion reported to French Poison Control Centers between 2009 and 2017, we investigated cases of poisoning due to manchineel fruit (from the Hippomane mancinella tree). This fruit is known to be responsible for oropharyngeal and gastrointestinal tract lesions and possibly hypotension and bradycardia (previously attributed to the presence of physostigmine). The most commonly observed clinical signs were oropharyngeal pain, abdominal pain, diarrhea and oropharyngeal irritation. No major gastrointestinal tract lesions were observed in the five cases in which upper gastrointestinal (GI) endoscopy was performed. One case of laryngeal edema and one case of bradycardia were observed, but analysis of the harvested fruits did not confirm the presence of physostigmine. Ingestion of manchineel fruit can cause mild abdominal pain and digestive irritation, requiring medical attention. Rarely, when several fruits have been ingested, severe oropharyngeal injury or hemodynamic disorders may require otorhinolaryngological consultation or cardiac monitoring for several hours, respectively.
