The abnormal retention of lipids by a cell or organ
In cellular pathology, steatosis is the process describing the abnormal retention of lipids within a cell. It reflects an impairment of the normal processes of synthesis and elimination of triglyceride fat. Excess lipid accumulates in vesicles that displace the cytoplasm. When the vesicles are large enough to distort the nucleus, the condition is known as macrovesicular steatosis; otherwise, the condition is known as microvesicular steatosis. While not particularly detrimental to the cell in mild cases, large accumulations can disrupt cell constituents, and in severe cases the cell may even burst. The risk factors associated with steatosis are varied, and include diabetes mellitus, protein malnutrition, hypertension cell toxins, obesity, anoxia and sleep apnea. As the liver is the primary organ of lipid metabolism it is most often associated with steatosis; however, it may occur in any organ, commonly the kidneys, heart, and muscle.
