Morquio-Ullrich syndrome

Related people

Typical symptoms and signs of Morquio’s syndrome; plus one or more features usually associated with Hurler’s syndrome, typically hepatosplenomegaly; corneal opacity; deafness, granulation in leukocytes.

This terminology was proposed by the German paediatrician Hans-Rudolf Wiedemann (1915-) to distinguish these patients from those with classic Morquio’s syndrome.

The eponym is unnecessary since it appears that in all patients with Morquio’s syndrome, if they survive to adolescence, these extraskeletal manifestations develop.
