Johanson‐Blizzard syndrome: Clinical and pathological findings in 2 sibs

Abstract

Here we report on 2 sibs with the Johanson-Blizzard syndrome (JBS). The first child died in the neonatal period, the autopsy showing presence of pancreatic ducts and islets surrounded by connective tissue and a total absence of acini. Morphologic changes suggested dysplasia leading to developmental failure, but early acinar destruction could not be ruled out. The second child had a constellation of abnormalities consistent with JBS, was managed surgically, and is maintained on replacement for his pancreatic enzyme and thyroid hypofunction. At 10 years, he is in a school for the hearing-impaired and is performing appropriately for his age.
