Fine structure and histochemistry of epithelioid cells in sarcoidosis.

The histochemistry and fine structure of epitheloid cells in sarcoidosis.

The fine structure of sarcoid and tuberculous granulomas.

The granulomas of sarcoidosis and non-caseating tuberculosis show similar cell-types: two forms of epithelioid cells, A and B, giant cells, lymphocytes and 'activated' mononuclear cells. The morphology of epithelioid cells suggests that they are primarily biosynthetic rather than phagocytic. The relationship of these various cells to each other is discussed and the following sequence of granulo...

Collagen nature of asteroid bodies of giant cells in sarcoidosis.

STAR-sHAPED INCLUIONS have been observed in multinucleated giant cells as far back as 1890.1 Perhaps the most comprehensive study of the asteroid bodies, as seen under the light microscope is that of Cunnngham' who e d in 1951 that "in tests for collagen, Masson's trichrome stain and Mallory's connective tissue stain showed negative results. Wilder's stain for reticuhlm wa uni negative. Cunning...
