  • Title: Ontogeny of renal dysplasia in Ivemark syndrome: light and immunohistochemical characterization.
    Author: Abbi R, Daum F, Kahn E.
    Journal: Ann Clin Lab Sci; 1999; 29(1):9-17. PubMed ID: 10074963.
    Abstract:
    Ivemark syndrome is a rare sporadic or autosomal recessive disorder characterized by pancreatic fibrosis, renal dysplasia and hepatic dysgenesis. There have been no data describing the renal changes during embryologic development in this syndrome. In this report, we document the pathological findings of the kidney in three subjects with Ivemark syndrome: 6 months, 21 weeks and 16 weeks, respectively. Kidneys of subjects and age-matched controls were examined by light microscopy and immunohistochemically for cytokeratin, AE1/AE3 and epithelial membrane antigen. Renal dysplasia in Ivemark syndrome becomes apparent at 16 weeks of gestation and progresses thereafter in severity. It is characterized by disturbance in glomerular differentiation, delay in tubular differentiation and abnormal expression of epithelial markers in glomeruli and tubules. Cytokeratin and epithelial membrane antigen expression of cysts is similar to that of the collecting ducts.
