A case of anaphylaxis after ingestion of Liparis tanakae

Liparis tanakae is a kind of fish in the northwestern Pacific Ocean and sometimes it is used for broth or frozen fish fillets on markets in Korea. A 45-year-old female patient visited Emergency Department because of facial edema, generalized urticaria, dyspnea, and hypotension after eating L. tanakae broth. She recovered after administration of epinephrine. Seven weeks later, she experienced generalized urticaria again after tasting a spoon of L. tanakae broth. In 2 months after recovery, the patient showed positive response to skin prick tests with L. tanakae extract. She also showed positive response to skin prick test with cod which did not induce any symptoms after oral ingestion. The patient was diagnosed as L. tanakae induced anaphylaxis based on the repeated clinical history and skin prick test results. We herein report the first case of L. tanakae induced anaphylaxis.
