It is known that the toad possesses several toxic substances in the skin and parotid glands. In the past, toad-venom poisoning has been reported from ingestion of toad soup, Kyushin and aphrodisiac pills, but poisoning from toad eggs is observed for the first time. The case of a healthy female who had previously eaten toad soup twice without any discomfort is reported. She developed gastrointestinal symptoms and life-threatening cardiac rhythm after ingestion of toad eggs. A transvenous temporary pacemaker was used promptly to prevent from lethal bradyarrhythmia. Hyperkalaemia was managed with insulin, glucose water and sodium bicarbonate. A digoxin-specific Fab fragment was administered to this young woman 4 h subsequent to her admission.
