Angina bullosa hemorrhagica is a rare disorder of unknown etiology characterized by the onset of bullous hemorrhagic lesions in oral cavity without relationship with vesiculobullous disorders, blood dyscrasias, or autoimmune conditions. Most times, it is not possible to identify the precipitating factor, but it has been associated to local trauma. Other factors related are inhaled corticosteroids and diabetes mellitus. This article presents a case of angina bullosa hemorrhagica in an emergency service of otorhinolaryngology. FSC, a 57-year-old male patient complained of a violet blemish in the palate with bulging (onset 2 hours before). He denied oral trauma, gingival bleeding, or melena. He stated that minutes before the lesion decreased in volume. He reported diabetes mellitus and hypertension, and denied other comorbidities. The oral examination showed rounded ecchymosis extending from the hard palate to the uvula. Transamin 500 mg was prescribed three times a day, for 5 days, and lead eating cold and pasty food. The patient was advised for a follow-up visit in 60 hours or before for reassessment. Three days after, the patient was asymptomatic. Oroscopy showed a pink lesion on the palatal mucosa without signs of bulging or bleeding. He was instructed to return in case of recurrence. The importance of this case is because of the extension of the lesion, not previously found in the literature, of a rare disease that had a fast resolution (3 days), distinct than the literature has shown, of 7 to 10 days.
