Angina bullosa hemorrhagica: a rare condition?

Resumo

Angina bullosa hemorrhagica is characterized by oral
mucosal blood-filled vesicles or blisters. These lesions, however, are
frequently asymptomatic and they are only observed when their content
is spilled over the oral cavity. Objective: The aim of this study was
to perform a retrospective evaluation of Angina Bullosa Hemorrhagica
(ABH) cases diagnosed in patients referred to the Diagnosis Center of
Oral Diseases of the Dentistry School of Federal University of Pelotas,
over a 4-years period. Material and methods: All the clinical records
from this period were reviewed and Angina Bullosa Hemorrhagica could
be diagnosed in 47 patients. The following information pertaining to
the patient and the lesion were collected from the dental record: gender,
age, ABH site, size of the lesion, presence of symptoms, bleeding,
likely predisposing factors, treatment and recurrence of the lesion.
Results: The results revealed 47 patients with clinical features of
ABH, 26 were female and 21 were male, with ages between 42 to 87
years. Thirty-six patients (76.6%) developed the lesion in the palate.
Pain was reported by 17 patients (36.2%) and bleeding by 19 patients
(40.4%). Seventeen patients (36.2%) reported the occurrence of the
lesion following trauma. Conclusion: It is possible to conclude that
although ABH has been traditionally described as a rare condition,
the data obtained in this study suggest a fairly high occurrence of
the disease.
