I would start with the first article. It's a PDF of a 2007 article titled "
Ear-nose-throat manifestations in Inflammatory Bowel Diseases" from the Annals of Gastrolenterology.

All of these articles say over and over how rare these manifestations are. Personally I think they are not really all *that* rare. I think they just go undiagnosed.
Take my son. His pediatrician said "it's just from dry air" when we first went to see him about the sores. But nothing we did made them better. the inside of his nostrils were nothing but bloody sores that didn't hurt.
They got worse and worse, finally tested positive for staph so he did oral antibiotics. Helped but the sores still didn't completely go away. Then, suddenly for no apparent reason, in a matter of days they healed up completely.
about 3 months later - suddenly the sores are back. No infection that time so we just did topical ointments to help prevent infection and, just like before, suddenly they were gone.
Went through that for about a year. His labs were good but not perfect.
Now it's been 9 months since the last round of nasal sores. Now his labs are perfect in every way.
Was it CD? Who knows.
Walks like a duck, quacks like a duck, looks like a duck - is it a duck?
