Behcet's disease presenting as recurrent oral aphthosis in a 9-year-old boy from Greece

We report a case of Behcet's disease in a 9-year-old boy from Greece, presenting with a history of recurrent ulceration of the oral cavity. Following inspection of the oral cavity, which revealed lesions on both the upper and lower labial mucosa, as well as a large ulcer on the apex of the tongue, the diagnosis of Behcet's disease was immediately suspected. The diagnosis was confirmed using the International Criteria for Behcet's Disease. Nevertheless, as multiple diseases can cause recurrent oral aphthosis, an extensive differential diagnosis was made, and pertinent tests were undertaken to exclude other causes of oral ulceration. The approach to a patient with Behcet's disease, as well as its various clinical presentations and complications, is discussed.
