Hemorrhagic Bullous Angina: A Case Report and Review of the Literature.

Hemorrhagic bullous angina (HBA) is described as the sudden onset of one or more bullous lesions in the oral cavity, not attributable to other vesiculobullous diseases, blood dyscrasias, or autoimmune and vascular diseases. These lesions occur almost exclusively in the oral cavity, particularly in the soft palate, and do not affect the masticatory mucosa. Here we present the case of a 57-year-old male who had a spontaneously ruptured hemorrhagic bulging in his soft palate diagnosed as HBA, along with discussion of the literature. In conclusion, HBA is a rare, benign, oral disease with low complication rates. Diagnosis is essentially clinical, and treatment consists of local hygiene and prevention of oral trauma.
