  metabolic histiocytoses; metabolic histiocytic infiltrations
  Definition : Infiltrative storage disorders (lysosomal storage diseases) are usually autosomal recessive disorders characterized by deficiency in specific enzymes.
  The diagnosis can often be made based on clinical findings, demonstration of specific enzyme deficiencies, and genetic analyses.
  Cytologic clues may also suggest the diagnosis. For example, the pathologic hallmark in Gaucher’s disease is the presence of large (...)
