Case for diagnosis. Ulcerated lesions: a diagnostic challenge in Behçet's syndrome.

This study reports the clinical case of a 42-year-old patient with ulcerated lesions who was followed up by general practitioners with the diagnosis of recurrent cellulitis. However, when referred to the Dermatology division a diagnosis of Behçet's syndrome was established based on clinical criteria. Although there are defined clinical criteria for this syndrome, sometimes its diagnosis can be challenging, due to lack of knowledge of the disease and extremely heterogeneous clinical phenotype.
