Arthrogryposis, renal dysfunction and cholestasis syndrome: report of five patients from three Italian families.

We report on five patients from three families with neurogenic arthrogryposis, cholestasis and tubular renal dysfunction. Despite a similar clinical picture the liver histology showed a broad pathological spectrum, ranging from pigment storage to parenchymal giant cell transformation and ductopenia. The findings are compared with those of other cases from the literature in search of a correct nosology of the syndrome characterized by arthrogryposis, renal and liver disease. CONCLUSION. We propose to consider the picture of arthrogryposis, renal tubular dysfunction and cholestasis as a single syndrome.
