Lipochrome (lipofuschin) pigments
These are the breakdown products within cells from oxidation of lipids and lipoproteins. They are the wear-and-tear pigments found most commonly in heart, liver, CNS, and adrenal cortex (zona reticularis). The less highly oxidized "ceroid" pigment of testis interstitium and seminal vesicle is another form of lipochrome.Lipochrome can be stained by Sudan black B, long Ziehl-Neelson acid fast, and Schmorl's methods. Lipochrome may also exhibit a strong orange auto fluorescence in formalin-fixed, unstained paraffin sections.
