Background: Angina bullosa haemorrhagica (ABH) is characterized by the recurrent appearance of blood blisters on the oral mucosa, mainly in adults' soft palate. In general, the blisters rupture spontaneously, lacking the necessity for biopsy. We report the clinical features of 23 ABH cases, emphasizing the clinical behavior and the management of these conditions. Material and Methods: A retrospective descriptive cross-sectional study was performed. A total of 12,727 clinical records of oral and maxillofacial lesions from four dental services in Brazil were analyzed. Clinical data were collected from the clinical records and evaluated. Results: The series comprised 12 males (52.2%) and 11 females (47.8%), with a mean age of 56.8 ± 14.6 years (ranging: 24-82 years) and a 1.1:1 male-to-female ratio. Most of the lesions affected the soft palate (n = 15, 65.2%). 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. The masticatory trauma was the most frequent triggering event. No patient had coagulation disorders. A biopsy was performed in only four cases (17.4%). Treatment was symptomatic with a favorable outcome. Conclusions: 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. The therapeutic approach is often focused only on the relief of symptoms. However, it can share some clinical features with more serious diseases. Therefore, clinicians must recognize these lesions to avoid misdiagnosis.(AU)

Background: Pigmented lesions are uncommon in the oral mucosa, and studies investigating the incidence andtypes of these lesions are desired to improve the diagnostic knowledge of clinicians. The aim of this study was toanalyze the distribution of oral pigmented lesions in a Brazilian population.Material and Methods: A retrospective descriptive cross-sectional study was performed. Oral pigmented lesionswere retrieved from the files of two oral and maxillofacial pathology services from Brazil over a 45-year period(1974-2019). The clinical data and the diagnoses of each case were retrieved and included in a Microsoft Excel®database.Results: From 77.074 lesions diagnosed in this period, 761 (0.99%) represented pigmented lesions of the oralmucosa, including 351 (46.1%) melanocytic and 410 (53.9%) non-melanocytic lesions, with a higher incidence infemales (73.2%) between the fourth and seventh decades of life. Amalgam tattoo (53.6%) represented the most common lesion, followed by melanotic macule (18.3%) and racial pigmentation (10.8%). Other pigmented lesionsincluded nevus (9.9%), post-inflammatory pigmentation (3%), melanoma (2.1%), melanoacanthoma (1.4%), smoker'smelanosis (0.4%), drug-induced pigmentation (0.3%), and melanotic neuroectodermal tumor of infancy (0.1%). Thebuccal mucosa was the most commonly affected site (25.2%), followed by the alveolar ridge (14.5%), and gingiva(11.8%).Conclusions: The current findings were similar to previous studies with minor differences due methodology andcharacteristics of the services from where lesions were retrieved. The knowledge of these data may contribute to abetter understanding of oral pigmented lesions and assist clinicians to better recognize and manage them.(AU)
