| Alder- Reilly Anomaly Large inclusions in leukocyte cytoplasm appear with Alder-Reilly syndrome. Inheritance patterns are not completely clear. The condition is characterized by larger than usual azurophilic and deeply violet staining granules clustered throughout the cytoplasm (even covering the nucleus)in all granulocytes. There are variations in which some lymphocytes and monocytes may be affected. These inclusions represent partially degraded mucopolysaccharides within lysosomes.Alder-Reilly bodies may be found independently of genetic mucopolysaccharidoses as an inherited anomaly (Jordan's anomaly). Cytoplasmic vacuoles of toxic origin are not present in Alder-Reilly cells. The background condition in Alder-Reilly syndrome is mucopolysaccharidosis with various types of bone and cartilage disorders, reported first in gargoylism, then in Hunter and Hurler syndromes. Accompanying conditions are hepatosplenomegaly, corneal opacities, and mental retardation. Reference: Brunning, Richard D.
