Dieulafoy's disease: a cause of massive hemoptysis that is probably underdiagnosed.

Dieulafoy's disease is a vascular anomaly characterized by the presence of a tortuous dysplastic artery in the submucosa. The condition was first described as a cause of gastrointestinal bleeding in the stomach. Recently, there have been a few reports of Dieulafoy's disease involving the respiratory tract. Herein, we report 2 patients with massive hemoptysis who were treated with surgical resection and later diagnosed with bronchial Dieulafoy's disease.
