Flushing associated with scombroid fish poisoning.

Scombroid poisoning is a form of toxicity caused by the ingestion of spoiled dark-flesh fishes, mainly of the scombroid family. The clinical picture is secondary to histamine toxicity, manifested as flushing, headache, palpitations, and abdominal cramps. The diagnosis is established on the basis of these typical clinical manifestations and fish-ingestion history. We report a case of a man with scombroid poisoning. He was diagnosed after presentation of two similar patients with the same epidemiological history.
