Angina Bullosa Hemorrhagica of the Oral Cavity: A Case Report.

Angina bullosa hemorrhagica (ABH) is a rare, benign condition that is characterized by a blood-filled blister in the oropharynx. This report describes the case of a 27-year-old male who developed a blister in the oral cavity that ruptured abruptly and resolved spontaneously. The diagnosis of ABH was made according to the diagnostic criteria of Ordioni et al. The core motive of this report is to demonstrate the clinical features and course of ABH to avoid misdiagnosis.
