Giant Angina Bullosa Haemorrhagica Associated with Severe Anaemia: A Case Report

Angina Bullosa Haemorrhagica (ABH) is a rare oral disorder characterised by blood-filled bullous lesions in the oral cavity and oropharynx. In 1933, Balina of Argentina first characterised this condition as traumatic oral haemophlyctenosis. Subsequently, Badham introduced the term ABH to describe the disorder. The condition is also referred to by alternative names, including localised oral purpura and stomatopompholyx haemorrhagica. The lesions appear acutely and are primarily distributed over the tongue and oral mucosa without any systemic involvement. They are frequently isolated and rupture quickly, leaving an ulcerated area. The clinical appearance of this lesion can be alarming for patients and poses a diagnostic challenge for clinicians, as it may closely resemble more serious conditions such as haematological disorders and other vesiculobullous diseases. Here, we present a 72-year-old female diagnosed with ABH, notable for the unusually large size of the lesion and its rare association with severe anaemia.
