A Case of Chronic Urticaria Related to Clonorchis Sinensis / 소아알레르기및호흡기학회지

ABSTRACT

Clonorchis sinensis infection is one of the most common parasitic infections that is widely distributed in Southern Korea as well as China, Japan, Taiwan, Hong kong, and Vietnam and countries in Eastern Asia. The disease is caused by the ingestion of infected raw or under- processed freshwater fish. The clinical manifestations depend on the number of flukes in a patient, the period of infestation, and the complications. We experienced a 10-year-old boy who had a history of ingestion of raw fresh-water Chinese mitten crab preserved in soy sauce and presented with chronic urticaria. The causal organism, Clonorchis sinensis, was found by the identification of parasite ova in stool. We report a rare case of chronic urticaria related to Clonorchis sinensis that was successfully treated with praziquantel and review the pertinent literature.
