It has been reported that some patients have been misdiagnosed with Crohns’ Disease, when in fact the correct diagnosis in their specific case was Threadworms.
Threadworm or pinworm is an infection by enterobius vermicularis parasite that occurs commonly in children. Symptoms of infection include an itchy bottom that is worse at night, reduced appetite, malaise, adult worms can be seen in the faeces and eggs may be seen around the anus. As the parasite lives in the GI tract it can mimic conditions such as Crohns disease.
