Gaucher disease a lysosomal storage disease. It is a rare thingy that may be seen in people that marry their cousins.

Pathology

  • Accumulation of glucocerebroside in monocytes/macrophages due to deficiency of glucocerebrosidase.[1]
  • Defect in acid beta-glucosidase gene (GBA gene).[2][3][4]

Subtypes

  • There are several types - all are autosomal recessive.[1]

Types:[5]

  • Type I: 99% of cases; no CNS involvement - survive to adulthood.
  • Type II: infantile onset - CNS degeneration + death at young age.
  • Type III: mixed of type I & type II.

Clinical

  • Pancytopenia - due to marrow replacement.
  • Hepatosplenomegaly (type I).

Microscopic

Features:[6][5]

  • Mononuclear phagocytes with abundant eosinophilic cytoplasm with subtle irregular lines (~0.5 micrometers in width).
    • Known as "crumpled tissue paper cells" / "crumpled tissue paper cytoplasm."[7]

Notes:

  • Crumpled tissue paper: crumpled tissue paper - image (123rf.com).
  • The textbook case may look crumpled... along with some mind altering drugs.
    • The typical case is:
      • Abundant macrophages with cytoplasm filled by very small (clear) vacuoles (~0.2-0.4 micrometres).

Images:

Stains

  • Material in "crumpled tissue paper cells": PAS +ve.[5]
