Just Passing Through

Abstract

A 54-year-old man presented to his primary care physician with a 6-foot-long tapeworm in a jar after noting the specimen in a bowel movement the previous day. For several days prior to passing the worm, he had loose, non-bloody stools without abdominal pain or nausea. His past medical history was remarkable for a remote beef tapeworm infection. He denied travel, but regularly dined on sushi at various San Francisco restaurants several times a week.
