[Tyrosinosis. A difficult diagnosis of late infancy]

Abstract

The Authors report an unusual case of tyrosinosis in which neonatal metabolic screenings were not performed and the diagnosis was made only at 4 years of age. The diet induced an improvement of cirrhosis but did not influence renal tubular damage. The authors stress the diagnostic differential elements against other cirrhogenic metabolic diseases and emphasize the prospectives of liver transplantation.
