An 11-year-old girl was referred to oral medicine with persistent facial swelling. She was diagnosed with orofacial granulomatosis (OFG) and was treated conservatively for 7 years, with no evidence of systemic illness. Aged 17 she re-presented with a flare up of her OFG, watery diarrhoea and fluctuating febrile episodes. Inflammatory markers were raised and an MR enterogram revealed terminal ileal Crohn's disease. This case highlights that OFG may precede the onset of intestinal Crohn's disease.
