Behcet syndrome: A rare cause of recurrent genital ulceration.

Behcet syndrome (BS) is a chronic relapsing multisystem vasculitis with skin findings with an important contribution of genetics. Here, we present a case of a 16-year-old male with a complaint of recurrent genital, and oral ulceration with skin lesions and a history of recurrent thrombophlebitis at the sites of venepuncture. There were no systemic manifestations. Pathergy test and HLA-B51 were negative. The diagnosis was confirmed based on the International Criteria for Behcet disease (ICBD) for BS. Tapering doses of systemic corticosteroid and colchicine showed promising response and regression of lesions.
