To report the clinical features of angina bullosa hemorrhagica (ABH) cases, emphasizing the clinical and therapeutic characteristics. A retrospective descriptive cross‐sectional study was performed in 3 oral and maxillofacial pathology services and 1 private practice in Brazil. Clinical data were collected from the clinical records and evaluated. The series comprised 12 males (52.2%) and 11 females (47.8%), with a mean age of 56.8 ± 14.6 years. Most of the lesions affected the soft palate (n = 15, 65.2%) and tongue (n = 6, 26.1%). Clinically, the lesions presented mainly as an asymptomatic (n = 17, 73.9%) blood-filled blister that ruptured after a few minutes or hours, leaving an erosion. When specified, the masticatory trauma was the most frequent triggering event. No individual had coagulation disorders. Treatment was symptomatic with a favorable outcome. ABH is still poorly documented in the literature, and its etiology remains uncertain. ABH mainly affects the soft palate of elderly adults and has a favorable evolution in a few days. However, it can share some clinical features with more serious diseases. Therefore, a careful clinical examination is essential to rule out possible autoimmune or hematologic disorders.
