A Case Report of Angina Bullosa Haemorrhagica

Angina bullosa Haemorrhagica (ABH) is a term that was first introduced by Badham in 1967 to describe a bullous disorder in which recurrent oral blood blisters appear in the absence of any identifiable systemic disorder. It is a disorder restricted to the oral mucosa characterized by the formation of blood blisters on slight trauma in the absence of blood dyscrasia, vesiculobullous disease or other systemic diseases. The incidence of the disease is not known. Pathological studies did not reveal new information about these lesions so the etiology of this disease is not fully understood. However, the use of inhaled corticosteroids is a factor for the onset or exacerbation. The incidence of hemorrhagic bullae in primary and secondary amyloidosis is known. The condition runs a benign course. The aim of this paper is to report a case of Angina bullosa haemorrhagica in a 65-year-old man with a medical history of minor thalassemia with the following clinical manifestations: formation of bullas containing blood on the lateral surfaces of the tongue and the hard palate with the recurrence of 2 to 3 months.
