Abstract

Angina bullosa haemorrhagica is the term used to describe benign subepithelial oral mucosal blisters filled with blood that are not attributable to a systemic disorder or haemostatic defect. It is a very rare condition. 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. We present a 50-year-old patient with angina bullosa haemorrhagica. Trauma by sharp cusp of adjacent tooth and metal crown were identified as aetiological factors in this case. Lesions healed after removal of the metal crown and rounding of the cusp. Therefore, recognition of the lesion is of great importance to dentists, to avoid misdiagnosis.
