Angina bullosa hemorrhagica - Oral Mucosal Lesion
This condition affects men and women equally and typically occurs in adults aged 50-70 years. The pathophysiology of ABH is unclear. While precipitating factors such as hot drinks, inhaled corticosteroids, trauma from an adjacent sharp tooth edge, chewing, or a dental procedure have been reported, around half of patients have no obvious precipitant. Some of the reported cases in the literature have had concomitant hypertension and diabetes mellitus. A few patients with drug-induced or idiopathic thrombocytopenia have been reported to develop ABH-like bullae.
