Recurrent episodes of angina bullosa hemorrhagica of the tongue

Angina bullosa hemorrhagica is a relatively rare lesion of uncertain etiology affecting the oral cavity and the oropharynx characterized by blood-filled blisters or bullae of varying size. The lesions are sudden in onset, usually asymptomatic and bullae often rupture leaving ulcers which heal without scarring. No specific treatment is usually advised since it is a self-limiting lesion. Rarely, larger lesions in the oropharynx may cause air obstruction and require immediate attention. The clinical presentation of this lesion may cause apprehension to the patient and diagnostic challenge to the clinician since they clinically mimic other serious disorders such as blood disorders and vesiculobullous lesions. An awareness among clinicians is needed to prevent misdiagnosis and unnecessary diagnostic procedures of this distinct entity.
