Aims: Organophosphorus pesticide poisoning occurs frequently in China and can be diagnosed easily based on the history of ingestion and the cholinergic toxic syndrome. Yet, when combined with other toxins, organophosphorus poisoning may appear different.
Methods: Here, we present a case of acute ethanol poisoning together with a dermal organophosphorus exposure.
Results: Based on the history and a misinterpretation of the physical examination, the patient was treated as an organophosphorus poisoning. Ultimately, serum analysis helped clarify the diagnosis.
Conclusions: Toxicologist should be aware of the error known as anchoring and take appropriate precautions to limit its occurrence.
