[Primary oral manifestation of Crohn disease]

We present a case of primary and histologically verified oral manifestation of Crohn's disease in a 26-year-old man, with bilateral, non-healing granulomatous ulcerations in the inferior alveolobuccal sulcus, following the use of tooth protection during the practice of martial arts. Typical gastrointestinal symptoms followed approximately two months the onset debut of oral manifestations. The results of rectum biopsy, radiological bowel examinations, and blood sampling were typical of Crohn's disease. Oral manifestations and gastrointestinal symptoms responded well to standard treatment. We direct attention to this disease in patients with non-healing oral oedema, ulceration, or granulation.
