[Angina bullosa haemorrhagica - an unusual blistering in the oral cavity].

Angina bullosa haemorrhagica (ABH; also: bullosa haemorrhagica oralis or "benign hemorrhagic bullous stomatitis") was first defined by Badham in 1967 as recurrent formation of blood blisters on the oropharyngeal mucosa as a result of mechanically traumatic irri- tation. A possible connection with previous damage to the mucosa due to general medical findings such as hypertension, diabetes mellitus or chronic inhalation of corticosteroids has not yet been confirmed.
