Angina bullosa hemorrhagica, a case report of an uncommon condition

Abstract

Introduction Angina bullosa hemorrhagica (ABH) is a rare benign disorder characterized by one or multiple blood-filled bullae in the oral cavity and oropharynx with a sudden onset. Lesions are mostly isolated characterized by rapid onset, development and healing process. Trauma, inhalation corticosteroids and diabetes are common factors in ABH development. Case report: In this article we are presenting 3 ABH cases for three different patients. All of them were presented to the dental clinic complaining of the sudden appearance of recurrent blood-filled lesions . They reported that the lesions shortly rupture with a self-limited bleeding after 1 to 2 days from their appearance. Complete remission is expected within 7 to 10 days. ABH should be differentiated from other vesiculobullous disorders and hematologic disease. Conclusion: The typical clinical presentation in addition to routine hematologic investigations is usually sufficient to diagnose ABH. Patient’s education and reassurance are mandatory. No treatment is required for such cases
