THAT the tapeworm, Dipylidium caninum, common in cats and dogs the world over, can occasionally be found in humans has long been known. The first reported instance in the United States was in 1903 and occasional cases have been reported since, but it is interesting that there has been an increasing number of reports in the last ten years. Turner,1 in 1962, in a case report and review of the literature, stated that there were over 100 cases reported in world literature, including at that time only 20 in the United States. All but six of them had been reported since 1959. There have been several reports since Turner's article of 1962.2 For the most part, occurrences in the United States have been reported from the south, but isolated cases in Maine, New York, Michigan, and Minnesota have been observed. None have been reported from the northwest area.
