- immunotactoids seen on histopathology
- Because immunotactoids may be composed of either immune complexes or monoclonal proteins, which are capable of forming tactoids or microtubules, the variability in the size and the orientation of the tactoids from one patient to another may be a result of concentration or biochemical composition of the protein similar to that described in cryoglobulinemia.2006, Korbet SM, Schwartz MM, Lewis EJ, “Immunotactoid glomerulopathy (fibrillary glomerulonephritis)”, in Clin J Am Soc Nephrol, volume 1, number 6, →DOI, →PMID, pages 1351–1356:
