A small digenetic trematode was found in the mucosa of the pharynx of a 57-year-old woman residing in Hikone City. The patient had complained of discomfortable sensation and mild pain of the throat. There was no sign of pharyngitis. The patient was cured of the symptoms by resecting the worm from the mucosa. The fixed and stained specimen revealed that the worm was flattened linguiform, measuring 8.45 mm in length and 2.95 mm in width. The intestine showed sinuous wall in the hind body of the worm, and was connected with the excretory bladder. The fully developed genital organs with egg-filling uterus were situated in the middle portion of the body. This worm was identified as Clinostomum sp. based on the morphological findings. The worm discovered in this case was larger than those which had been reported so far as the cases of human. This report is the sixth human case of the genus Clinostomum infection in Japan.
