Behçet's disease in East African patients may not be unusual and is an HLA-B51 negative condition: a case series from Mayotte (Comoros).

Objective: We aimed to report the presence of Behçet's disease in patients of East African ancestry, where there have been very few reports of the disease.

Methods: Case series of 14 patients, all of whom were born in the Comoros, reporting to the single primary general medicine department of Mayotte's island since 1998. All the patients but one satisfied the international group study criteria for Behçet disease.
