Abstract

We report a case of clinical features corresponding to Eosinophilia-Myalgia syndrome, with no causal relationship with L-tryptophan. Since the epidemic of L-tryptophan associated Eosinoghilia-Myalgia Syndrome in 1989, only 2% of the cases were found not to be related to L-tryptophan in America.

We believe that this is the first case report of Eosinophilin-Myalgia Syndrome not related to L-tryptophan in Korea.
