Humans may be an accidental host if the infective stage, the cysticercoid larva, is ingested.1,2 Although rare, it is more commonly seen in infants and children.2-5 This case study involves an infant misdiagnosed with pinworm infection twice before a laboratory evaluation was able to confirm Dipylidium caninum. Accurate diagnosis is important, as treatment for pinworm infection will not eliminate Dipylidium caninum.
