Abstract :
T he oral cavity plays a crucial role in overall health, with certain oral lesions potentially indicating underlying conditions. Angina bullosa hemorrhagica (ABH) is a rare, benign oral mucosal disorder characterized by spontaneous blood-filled bullae unrelated to systemic diseases or bleeding disorders. This case report aims to describe a clinical presentation and management of a patient with recurrent ABH. A 17-year-old patient presented with a blood-filled lesion on the maxillary left buccal mucosa, persisting for one week, causing discomfort while chewing, with a history of a similar episode nine months back. No systemic or hematologic abnormalities were detected. Clinical examination revealed a solitary, tense, blood-filled bulla. Histopathology confirmed the diagnosis of ABH, ruling out other vascular or inflammatory lesions. There are no established guidelines for managing this condition. In the present case, an excisional biopsy was performed to distinguish it from other blood-containing bullae and alleviate discomfort. Follow-up was carried out at 15 days, 6 months, and 1 year. In conclusion, ABH is a rare but significant condition requiring accurate diagnosis to avoid diagnostic dilemmas and to prevent unnecessary treatments. Awareness of its clinical features helps clinicians differentiate it from other oral vesiculobullous disorders, ensuring appropriate patient management.
