Double pylorus in a patient with Behçet's syndrome.

We report a patient with Behçet's syndrome who presented with upper gastrointestinal haemorrhage. Gastroduodenoscopy showed a gastroduodenal fistula which caused the appearance of double pylorus in the antrum. The possibility of peptic ulcer disease related to non-steroidal anti-inflammatory drug use or Behçet's syndrome itself, as the cause of this rare condition in this patient is discussed.
