<unk> s are a rare finding, and when found they are suggestive of a poor prognosis, hence the colloquial term death crystals. A 2018 review found that 56% of patients died shortly after the<unk> s were first identified (usually within two weeks). However,<unk> s are of limited utility for predicting mortality because they are usually found in severely ill patients whose poor prognosis is already evident for other reasons by the time the crystals are detected. The<unk> s were once hypothesized to be bile products phagocytized during fulminant hepatic injury, due to the high incidence of<unk> s observed in cases of acute hypoxic and ischaemic hepatitis. However, recent studies have highlighted that the<unk> s stain positive for Oil Red O as opposed to bile stains, suggesting high lipid content. Additionally, some cases with<unk> s were not associated with notable hepatic injury. Currently, it is suggested that<unk> s are more likely to be phagocytized products of lysosomal degradation related to tissue injury.
