This report describes 3 cases of juvenile dermatomyositis (juvenile DM) com
plicated by cholestasis. All 3 patients had typical features of juvenile DM
, and all developed a cholestatic syndrome within the initial months of the
ir disease. Liver biopsy revealed mixed (cytoplasmic and ductal) cholestasi
s with no abnormalities in the intrahepatic ducts in all 3 cases. Cholestas
is improved or was completely reversible upon treatment with prednisone. In
the 2 patients who could be followed up long term, no sequelae remained. T
he possible role of inflammation in the pathogenesis of cholestasis in juve
nile DM is discussed.
