Recurrent aphthous stomatitis (RAS) is the most common chronic oral mucosal lesion affecting up to 25% of population. The diagnosis is based on well-defined clinical characteristics but the precise aetiology and pathogenesis remains unclear.

The systemic treatment is indicated in patients with continuous and aggressive manifestation, what is extremely rare in children. The present article provides a review of the current concept and knowledge of the aetiology, pathogenesis, and management of RAS in paediatric population.
