Angina bullosa hemorrhagica is characterized by acute blood blisters, mainly on the soft palate. Elderly patients are usually affected and lesions heal spontaneously without scarring. The pathogenesis is unknown, although it may be a multifactorial phenomenon. Trauma seems to be the major provoking factor and long term use of steroid inhalers has also been implicated in the disease. No underlying hematologic or immunopathogenic disorder has been found. Treatment is symptomatic.
We present a 67‐year‐old patient with recurrent oral blood blisters which were diagnosed as angina bullosa hemorrhagica. Trauma by dental injections and use of steroid inhalers were identified as etiologic factors in this case. Erosions healed within a week.
Although this is a benign condition, it may result in acute airway obstruction. Recognition is, therefore, of great importance for dermatologists.
