Angina Bullosa Hemorrhagica

Angina bullosa hemorrhagica (ABH) is an intraoral blood-filled blister. ABH usually occurs unrelated to any systemic disease. However, very rarely, one should obtain a platelet count. We had one case at our institution where an older gentleman presented with just one of these and his platelet count was < 10k!


An intramural blood blister suddenly appears. It may be solitary or multiple. They may occur anywhere in the mouth, e.g. the palate, buccal mucosa or tongue, but they do not seem to occur on the gums. Within hours to days, the blister breaks, leaving a shallow ulcer that heals in 1-2 weeks without scarring.


No treatment is needed. The lesions will heal uneventfully. As noted above, a workup for a bleeding diathesis may be indicated, especially in recurrent or severe cases.
