Abstract
A group of 14 individuals suffering from traumatic haemorrhagic bullae of the oral mucosa, predominantly located in the soft palate area and tongue was reviewed in this retrospective study. Recurrences occurred in four individuals.
Basic laboratory parameters (blood count) were normal in all patients. Despite characteristic history, typical clinical signs and course, traumatic haemorrhagic bullae remain a relatively uncommon, atypical and often misinterpreted acute disease of the oral cavity.
The diagnosis could be difficult but the differentiation of this benign local mucosal problem from more serious group of vesicobullous, haemorrhagic and ulcerative diseases of the oral mucosa is mandatory. The necessity of additional diagnostic procedures was also discussed.
In mucosal lesions associated with typical clinical course and relevant anamnesis, biopsy should not be required. Haematological tests were recommended in all individuals with recurrence of the disease and/or lack of relevant anamnestic data.
