Case #263 - November, 2009

A 35-year-old man from Nepal presented at a hospital with recurring cholangitis; the patient had been experiencing symptoms for the previous six months. An MRI revealed two lesions in the liver, measuring approximately 5 centimeters long by 2 centimeters wide. Both lesions had cystic as well as solid components. An endoscopic retrograde cholangiopancreatography (ERCP) was also performed in the common bile duct, revealing flat leaf-shaped objects (Figures AB). The objects were removed and collected in 10% formalin; they measured on average two centimeters in length (Figure C). One of the specimens was sent to a reference laboratory for identification, where it was stained with carmine (Figure D). What is your diagnosis? Based on what criteria?
