A complete but abnormal form of Taenia worm was obtained from an 18-year-old male student in Cheju Island, Korea, which has been known as a heavy endemic area of Taenia saginata and few of T. solium. There was an apical hookless eminence in the scolex, longitudinal white line along the middle portion of entire strobila, double genital pores and several lateral buddings from the strobila. It was considered an abnormal form of Taenia species, probably T. saginata.
