Angina bullosa hemorrhagica (ABH) is a rare oral disorder characterized by blood-filled bullous lesions in the oral cavity and the oropharynx in the absence of an underlying systemic, haematological or mucocutaneous condition. The presentation of the lesions is acute and located on the lining mucosa, mainly on the soft palate. Often, these lesions are single and rupture easily leaving an ulcerated area. In this study, we present 4 ABH cases in 3 women and 1 man and we discuss the main clinicopathological characteristics. The characteristics of this disorder are important to recognize in order to differentiate the lesions from other oral bullous conditions of the oral cavity such as mucocutaneous disorders or blood coagulation disorders.
