Talk about residual bodies.

AKA lipofuscin pigment granules, larger than primary lysosomes and irregular in shape, derive from secondary lysosomes after the end of digestion, because digestion is incomplete, they produce wastes enclosed by a membrane making the residual body, which are expelled outside through exocytosis. But some residues are expelled into cytosol in long living cells, those kept are called lipofuscin granules composed of lipid (yellow brownish) which disturbs the cell metabolic activity and causes aging.
