Recently several cases of human infections with the double-pored tapeworm, , have been reported. It is well known that this tapeworm is a cosmopolitan parasite of dogs and cats and over 100 human infections, mostly in children, have been reported from many areas of the world. To date in this country there have been only eighteen cases of dipylidiasis recorded. The two noted here are from Texas and Florida thus raising the total to twenty.

The first of these two cases (M. T.) was diagnosed in 1954 and was referred to one of us (GWH) for diagnosis by a physician practicing near San Antonio, Texas. The patient was a 7-year-old girl whose only symptoms were periodic, generalized abdominal pain especially when at stool, general irritability, and perianal pruritus. Because of the pruritus pinworm had been suspected and several scotch tape preparations had been submitted for examination.
