   • 1868, Felix von Niemeyer, J. L Parke, Clinical Lectures on Pulmonary Phthisis, Moorhead, Simpson & Bond, page 3:

     But we can no longer regard the mere fact of these diffuse condensations of the lung becoming yellow and caseous as an evidence of their tuberculous nature, especially since the pathological anatomists, and among them Virchow, have shown that formations of the most different kind, having not the slightest connection with tubercule— as, for example, old cancerous masses, lymphatic glands swollen by a hyperplasia of cells, hæmorrhagical infarctions, abscesses, &c.— undergo exactly the same caseous transformation.

   • 2023, Simon Mays, “The Macroscopic Study of Human Skeletal Paleopathology” (chapter 2), in The Routledge Handbook of Paleopathology, Routledge, →DOI, →ISBN, page 30:

     […] there has been recognition that porosity of the orbital roofs and cranial vault may arise due to a variety of different causes. These include rickets and scurvy, where it occurs due to different pathophysiological mechanisms […]. In vitamin D deficiency, it arises as a result of deficient mineralization of the growing bone surface, in scurvy as a result of deposition of porous new bone and/or vascular inflammatory response; versus diploic hyperplasia coupled with resorption of overlying cortical bone in anemia.
