Introduction: Behcet disease (BD) is an autoimmune disorder characterized by oral aphthosis, genital aphthosis, ocular lesions, and arthritis. However, other fatal complications are often misdiagnosed, which implies that the early diagnosis of the disease is important for a good prognosis. Patient concerns: A 51-year-old man complained of hematemesis for 5hours and syncope once. Diagnosis: BD as demonstrated by esophageal ulcer and aortic aneurysm rupture. Interventions: Surgeries were conducted to repair the thoracic aortic aneurysm, proton-pump inhibitor was used to reduce acid secretion, antibiotics were applied for anti-infective therapy, and immunosuppressor was administered to control the injuries of BD. Outcomes: The patient was discharged and his medication dosage was reduced gradually until the minimum maintenance dose. In the follow-ups, the gastric ulcer and vascular aneurysm were not found. Conclusion: We presented a rare case of BD with the concurrence of huge esophageal ulcer and thoracic aortic aneurysms rupture, which helped us to diagnose BD at the early stage, while confronting atypical manifestations.
