  • Title: Immunohistochemical and ultrastructural features of Gaucher's cells--five case reports.
    Author: Bogoeva B, Petrusevska G.

    Abstract:
    Gaucher's disease is an autosomal recessive lysosomal storage disease resulting from glucocerebrosidase deficiency. In this report, five patients with adult Gaucher's disease are described. The clinical course of these patients was characterized by progressive diffuse aseptic necrosis in the large bones, so-called Erlenmeyer's flask deformity, and hepatosplenomegaly. Splenomegaly was accompanied by hypersplenism with anemia and thrombocytopenia, therefore splenectomy was performed. The diagnosis of Gaucher's disease was based on the finding of Gaucher's cells on bone marrow biopsy. Tissue blocks were cut and routinely processed. Slides staining for iron (Peris' blue) and PAS (periodic acid--Schiff) including immunohistochemical staining for CD68 and HLA-DR was performed in all five cases. Gaucher's cells were seen as large cells with granular or fibrillar distended cytoplasm, with the characteristic 'wrinkled tissue paper' appearance, and eccentric nuclei. PAS staining showed strongly positive granular or fibrillar material in the cytoplasm. Immunohistochemical stain for CD68 and HLA-DR helped identify isolated Gaucher's cells, which are hystiocytic in nature. This stain accentuates their fine linear striations. Small pieces were ultrastructurally analyzed.
