Pathology of Gaucher's Disease

Dr Sampurna Roy MD                       

 

                                                                                                                      

 

Gaucherís disease is due to an absence of B-glucosidase and results in the accumulation of glucocerebroside in the reticuloendothelial cells.

The red pulp of the spleen, sinusoids and medullary portions of lymph nodes, sinusoids of the liver and bone marrow are particularly involved.

The Gaucher cell is a large, sometimes multinucleate cell, and has a cytoplasm, which stains bluish-gray with Giemsa. 

The cytoplasm has the appearance of "crumpled tissue paper", particularly noticeable with PAS staining.

Like all storage cells and histiocytes with activated lysosomal systems there is strong acid-phosphatase activity.

The cytoplasm also shows autoflourescence in unstained paraffin sections and there is variable birefringence in unstained frozen sections.

The cell morphology contrasts with the storage cells of Niemann-Pick disease which typically shows fine cytoplasmic vacuolation.
