title: Extrapulmonary lymphangioleiomyomatosis: an unusual cause of biliary tract obstruction.
abstract: We present a patient who was diagnosed with retroperitoneal lymphangioleiomyomatosis (LAM) and who developed biliary tract obstruction caused by LAM in the papilla of Vater. After endoscopic retrograde cholangiopancreatography (ERCP) and papillotomy, the patient's liver enzymes normalised. Disease progression was slowed down with gosereline and interferon alpha 2b (IF N-alpha 2b). In patients with LAM and signs of biliary tract obstruction, disseminated LAM should be considered. IFN alpha 2b can be a useful treatment in patients with widespread LAM.
