Angina bullosa hemorrhagica: report of 4 cases.

Angina bullosa hemorrhagica is characterized by the sudden appearance of solitary or multiple hemorrhagic blisters on oral mucosa, with diameters ranging from 2 mm to 3 cm. The soft palate is most commonly affected, but angina bullosa hemorrhagica may also appear on the buccal mucosa, lips and tongue border. Clinically, the blisters have a dark red to purple appearance, and may or may not be painful. The blisters usually break, releasing bloody content and leaving an ulcer surface that heals within 7 to 10 days. In this article the authors describe four cases of angina bullosa hemorrhagica attended in Stomatology Department of Dental School, Sao Paulo State University. In case 1, a 29-year-old male presented with a sudden hemorrhagic blister on the soft palate. A drainage was performed and after seven days of follow-up the patient reported no symptoms. In case 2, a 63-year-old male presented complaining of a blister on the palate six days earlier that had spontaneously broken. General exam showed hypertension under medical control. An incisional biopsy was performed and after seven days follow-up the healing was completed. In case 3, a 61-year-old male arrived complaining of a sudden appearance of an hemorrhagic blister on the soft palate that had spontaneously broken. The patient had systemic hypertension under medical control. The ulcer healed in 10 days follow-up. In case 4, a 49-year-old woman presented complaining of pain and an ulcer on the soft palate. The patient reported the rapid onset of a blood blister during a meal that broke in few minutes. The resolution occurred after 14 days. Angina bullosa hemorrhagica seems to be more common than reported in the literature and knowledge of the condition is important to right diagnosis and approach when necessary.

Surgical management of an infected aggressive florid cemento-osseous dysplasia. Report of a case.

Florid cemento-osseous dysplasia (FCOD) is a quite rare condition presenting in the jaws and is most seen in middle-aged black women, from the 4th decade of life on. The pathogenesis of the cemento-osseous dysplasias remains unknown; however, they seem to represent some kind of reactional or dysplastic process. We describe an aggressive case of infected florid cemento-osseous dysplasia (IFCOD) in a 47-year-old black woman. Extensive dysplastic lesions affected all jaw quadrants and radiographic features showed images of irregular radiopaque multilobular masses, peripherally lined by a radiolucent layer. We decided to keep the patient in the hospital in order to perform endovenous medication, hydration, drainage and general care. The surgery planning would be started as soon as regression of the acute feature was observed. Histopathologic analysis revealed the lesion was composed by osseous and cementoid tissues, being its diagnosis compatible with FCOD. The surgical procedure was accomplished with the patient under general anesthesia. It was opted for the excision of the lesion in all quadrants, with sequestrectomy and total dental extraction and remodelling of the alveolar ridges. After 9 months of follow-up the patient is still undergoing clinical control, presenting healing within the expected patterns. Symptomatic cases follow-up should be lasting and periodical, since there are reports of recurrence.
