The ultrastructure of glomerular haematoxylin bodies.

The ultrastructural features of haematoxylin bodies, present in a patient with active lupus glomerulonephritis, appear to include cellular elements, especially dense chromatin of probable neutrophil leucocyte origin and electron-dense, immune complex-like material. Although the participation of immune complexes in the formation of haematoxylin bodies has been previously proposed, this is the first reported demonstration of such deposits in haematoxylin bodies.
