Aphthous stomatitis as the debut of Crohn’s disease

Crohn’s disease is an immune-mediated disease characterized by non-specific granulomatous transmural inflammation with segmental damage to any part of the gastrointestinal tract with the formation of extraintestinal and systemic complications. Clinical observation of patient I., 23 years old, a student who was sent for consultation to a gastroenterologist in the direction of a dentist, is presented. Active examination of the gastrointestinal tract during the inspection did not show any complaints. He considers himself ill for 6 months, when he first complained of pain in the neck, sore throat, and body temperature rise to 37.4–37.5 °C, mostly in the evening. Were treated by an otolaryngologist and a dentist without significant effect. In this connection, a biopsy of the ulcerative defect of the left retromolar region was performed, revealing noncaseating granulomatous inflammation. A follow-up examination by a gastroenterologist with colonoscopy and biopsy made it possible to establish Crohn’s disease as the true cause of aphthous stomatitis.
