Angina bullosa haemorrhagica: presentation of eight new cases and a review of the literature.
Angina bullosa haemorrhagica (ABH) describes the acute and sometimes painful onset of oral blood-filled vesicles and bullae not attributable to blood dyscrasia, vesiculo-bullous disorders, systemic diseases or other known causes. The haemorrhagic bullae spontaneously burst after a short time resulting in ragged, often painless, superficial erosions that heal spontaneously within 1 week without scarring. Although the pathogenesis is still unclear, ABH seems to be a multifactorial phenomenon: dental or functional trauma seems to be the major provoking factor. The lesions of ABH can be easily confused with other mucosal diseases. It is important that the presentation of this benign disorder is distinguished from other more serious disorders with similar presenting features. The aim of this paper is to report the clinical features of eight cases of ABH, in an attempt to distinguish ABH from other blistering diseases of oral mucosa and to describe their management.
