Osteonecrosis of the jaw fatty degeneration and/or necrosis, often with pooled fat from destroyed adipose cells (oil cysts) and with marrow fibrosis (reticular fatty degeneration)"" are seen. These changes are present even if ""most bony trabeculae appear at first glance viable, mature and otherwise normal, but closer inspection demonstrates focal loss of osteocytes and variable micro cracking (splitting along natural cleavage planes). The microscopic features are similar to those of ischaemic or aseptic osteonecrosis of long bones, corticosteroid-induced osteonecrosis, and the osteomyelitis of caisson (deep-sea diver's) disease"". In the cancellous portion of femoral head it is not uncommon to find trabeculae with apparently intact
Moore v. Regents of the University of California because of the potentially fatal amount of swelling in Moore's spleen. Moore signed a written consent form, authorizing the procedure. It said the hospital could "dispose of any severed tissue or member by cremation," and his spleen was removed by surgeons, who were not named as defendants, at UCLA Medical Center. Moore's blood profile returned to normal after only a few days, and further examination of his spleen led Golde to discover that Moore's blood cells were unique in that they produced a protein that stimulated the growth of white blood cells, which help to protect the body from infections.
