Angina bullosa hemorrhagica an enigmatic oral disease

Variations of oral anatomy and common oral lesions

Several topics related to the oral cavity are briefly addressed in this article, from anatomical variations that, when recognized, avoid unnecessary investigations, to diseases that affect exclusively the mouth, mucocutaneous diseases, as well as oral manifestations of systemic diseases. A complete clinical examination comprises the examination of the mouth, and this approach facilitates clinical practice, shortening the path to diagnosis in the outpatient clinic as well as with in-hospital patients. The objective of this article is to encourage the examination of the oral cavity as a useful tool in medical practice, helping to recognize diseases in this location.

Angina bullosa hemorrhagica

Angina bullosa hemorrhagica (ABH) is a term used to describe acute, subepithelial oral mucosal blisters filled with blood without any systemic disorder or hemostatic defect. The diagnosis of ABH is largely clinical, and includes elimination of other diseases at histology. We present a 24-year-old patient suffering from ABH with some clinical peculiarities. Recognition of ABH is of great importance to dermatologists, to avoid misdiagnosis.
