Angina Bullosa Hemorrhagica - A Case Series.

Angina bullosa hemorrhagica (ABH) is an oral subepithelial blood blister with poorly understood etiopathogenesis, which is not attributable to blood dyscrasias or vesiculobullous disorders. These hemorrhagic bullae spontaneously rupture within minutes to hours, resulting in ragged, often painless, superficial erosions that heal spontaneously within 1 week without scarring. The lesions are usually solitary, and sometimes cause extreme anxiety in patients. Treatment is generally symptomatic. We report a series of four such patients. No treatment was given, except for reassurance and anxiolytics.
