Coinfection with Hymenolepis nana and Hymenolepis diminuta infection in a child from North India: A rare case report

Hymenolepiasis is considered the most common tapeworm infection throughout the world infecting 50–75 million people. Hymenolepis diminuta infection is not commonly reported in human beings as compared to Hymenolepis nana because it is primarily a parasite of rats and mice. There are few case reports of H. diminuta in the Indian population. To the best of our knowledge, not a single case of coinfection with H. nana and H. diminuta has been reported from India. We present here a rare case report of coinfection of H. nana and H. diminuta in a 4-year-old male child from a semirural area of India who presented with acute and severe colitis.
