Abstract
Angina bullosa hemorrhagica (ABH) is characterized by development of acute onset of painless solitary or multiple blood-filled vesicles or bullae in oral mucosa which are not attributed to blood dyscrasias, vesiculobullous disorder, and systemic diseases. These lesions rupture spontaneously to form ragged, often painless, superficial erosions that heal spontaneously within 1 week without scarring. Trauma appears to be the most common identifiable precipitating factor. We report a case of ABH to emphasize the importance of recognition of this relatively rare benign condition and to differentiate it from other dermatological and systemic causes of oral blisters.
