Angina bullosa hemorrhagica: A rare and benign oral mucosal disorder – A case report.

A 17-year-old patient presented to the Department of Pediatric Dentistry with a blood-filled, red swelling on the maxillary left buccal mucosa, persisting for the past 1 week. The patient reported previous episodes with a similar lesion in the same area 2 months ago, which ruptured after 2 days, resulting in an ulceration that healed within a week without scarring. However, the lesion reappeared in the same region 1 week ago. The patient had no relevant medical history, no family history, no toxic habits, and no known allergies. No notable extraoral abnormalities were detected.
