Angina Bullosa Hemorrhagica Clinical Presentation

History
- The blisters of angina bullosa hemorrhagica predominantly affect middle-aged or elderly people without sex predilection.
- Some patients with angina bullosa hemorrhagica describe a stinging pain or burning sensation immediately before the appearance of the blood blister.
- The blisters last only few minutes and then spontaneously rupture, leaving a shallow ulcer that heals without scarring, discomfort, or pain. Note the images below.
A 42-year-old man with the sudden appearance of angina bullosa hemorrhagica. The patient experienced pain a few minutes before the bulla appeared. He had a history of 3 similar previous episodes at the same site. Because the lesions only stay intact for a short duration, the patient took the picture using his own cellular phone.

Image shows 24 hours after the initial presentation of angina bullosa hemorrhagica. - Patients do not report a tendency to bleed at other sites.
- Family history generally is noncontributory to angina bullosa hemorrhagica. Grinspan et al[2] reported that 44% of his patients in a series of 24 cases published in 1999 suffered from type II diabetes, hyperglycemia, or family history of diabetes. No conclusive evidence of a cause-and-effect relationship between the presence of angina bullosa hemorrhagica and glucose metabolism exists.
Physical
- The lesions of angina bullosa hemorrhagica reach an average size of 1-3 cm in diameter.
- The soft palate is the most commonly affected site in angina bullosa hemorrhagica.[3]
- Occasional lesions have been reported in the buccal mucosa and tongue.
- The anterior third is most commonly affected in the tongue.
- Approximately one third of the patients exhibit lesions in more than one location.
- The oral mucosa attached to bone (ie, masticatory mucosa represented by the hard palate and gingiva) is not affected.
- Similar lesions in other mucous membranes or the skin have not been reported.
Causes
- A report of 16 cases affecting the soft palate described hypertension as the most frequent underlying systemic condition (6 of 16 subjects); however, its relationship remains speculative, as hypertension is common in adults.[9]
- A causative factor is not identified in approximately 47% of patients with angina bullosa hemorrhagica.
