Cholestatic jaundice and bone lesions in an elderly woman.

University of Pittsburgh Medical Center, PA, USA.

BACKGROUND: A 74-year-old Caucasian female presented with jaundice, clay-colored stools, diarrhea, and fatigue of 3 months' duration, accompanied by a weight loss of 6.8 kg. Physical examination demonstrated mild hepatomegaly. Initial blood work revealed abnormal liver biochemistries with a cholestatic pattern. An abdominal CT scan showed intrahepatic bile-duct dilatation without masses but with multiple lytic and blastic bone lesions. A sacral bone biopsy established the diagnosis. INVESTIGATIONS: Endoscopic ultrasound, endoscopic retrograde cholangiopancreatography, CT scan, bone biopsy and liver biopsy. DIAGNOSIS: Systemic mastocytosis affecting the biliary system resulting in a primary-sclerosing-cholangitis-like picture combined with diffuse blastic and lytic bone lesions. MANAGEMENT: Biliary stenting, histamine 1- and 2-receptor blockers, and chemotherapy (cladribine).
