Abstract
Angina bullosa hemorrhagica (ABH) is a rare, benign disorder characterized by one or multiple blood-filled blisters in the oral cavity (mainly soft palate, and sometimes oropharynx) with a sudden onset, that may lead to a potentially threatened airway. The most common hypothesis of its unknown origin is mild trauma. This lesion can easily be confused with other mucosal diseases or hematological disorders. Knowledge of the condition is important for correct diagnosis and treatment. Incision of the bulla, intubation, or even tracheotomy may be indicated. Here we present a case of 35-year-old woman with a complaint of dysphagia without dyspnea. During oral examination, a blue and/or purple blister on the soft palate was present. On endoscopic examination, an edematous uvula was observed, without other abnormalities. Eventually, the blister ruptured spontaneously and healed within one week without any sequelae.

We describe an overview of the etiology, pathophysiology, diagnostic workup, and treatment of ABH
A healthy 35-year-old female with no relevant medical history was presented at the emergency department with a swelling in her mouth after eating an unsalted assorted nut mix. She described that within seconds after eating, a swelling developed in the back of her throat, which led to dysphagia
Summary
Angina bullosa hemorrhagica (ABH) is a relatively rare entity with an overall good prognosis. A healthy 35-year-old female with no relevant medical history (no known allergies and no medication use) was presented at the emergency department with a swelling in her mouth after eating an unsalted assorted nut mix. She described that within seconds after eating, a swelling developed in the back of her throat, which led to dysphagia. Given the location of the lesion and the possibility of a threatened airway, the patient was admitted for overnight observation. The specific presentation, location, and fast regression of the lesion and exclusion of other possible hematological diseases led to the diagnosis of ABH.
