Angina bullosa haemorrhagica is a benign, usually painless lesion characterized by the sudden formation of haemorrhagic bullae in the oral mucosa. Clinically, it is in the form of bubbles filled with blood. In a short period of time, the lesions become ulcerated and usually heal without scarring within a week. Although the etiology of this disease, which is seen as recurrent lesions is not known, it is thought that factors such as local trauma and inhaler steroids are effective in its formation. Mucosal lesions are observed especially in the intraoral region. It is important for dentists to prevent misdiagnosis, to detect lesions and to eliminate etiological factors. Here, we present a patient with short-term, haemorrhagic, painless blisters resembling angina bullosa haemorrhagica in the oral mucosa as it is a rare disease.
