| caseous degeneration | Caseation necrosis, necrosis characteristic of certain inflammations (e.g., tuberculosis, histoplasmosis), which represents necrosis with loss of separate structures of the various cellular and histologic elements; affected tissue manifests the friable, crumbly consistency and dull, opaque quality observed in cheese.

| vitelliform degeneration | Degeneration in Best's disease, with the macular region of each eye occupied by a bright orange-yellow circular deposit resembling an egg yolk, followed by scarring; autosomal dominant inheritance. Synonym: vitelliruptive degeneration. (05 Mar 2000) |

| reticular degeneration | <ophthalmology> Severe epidermal oedema resulting in multilocular bullae. (05 Mar 2000) |
| retinal degeneration | <ophthalmology> A retrogressive pathological change in the retina, focal or generalised, caused by genetic defects, inflammation, trauma, vascular disease, or aging. Degeneration affecting predominantly the macula lutea of the retina is macular degeneration. (03 Jul 1999) |
| retrograde degeneration | The series of changes in a neuron following the severing of its axon, including central chromatolysis with displacement of the nucleus. (12 Dec 1998) |
| granular degeneration | Swelling of cells due to injury to the membranes affecting ionic transfer; causes an accumulation of intracellular water. Synonym: albuminous swelling, granular degeneration, hydropic degeneration, parenchymatous degeneration. (05 Mar 2000) |
| granulovacuolar degeneration | Degeneration of hippocampal brain cells in elderly persons, characterised by basophilic granules surrounded by a clear zone in hippocampal neurons; occurs more frequently in Alzheimer's disease. (05 Mar 2000) |

| Monckeberg's degeneration | Arterial sclerosis involving the peripheral arteries, especially of the legs of older people, with deposition of calcium in the medial coat (pipestem arteries) but with little or no encroachment on the lumen. Synonym: medial arteriosclerosis, Monckeberg's calcification, Monckeberg's degeneration, Monckeberg's medial calcification, Monckeberg's sclerosis. (05 Mar 2000) |
| waxy degeneration | Infiltration of amyloid between cells and fibres of tissues and organs. Synonym: waxy degeneration. (05 Mar 2000) |
| colliquative degeneration | An obsolete term for liquefaction degeneration. (05 Mar 2000) |
| colloid degeneration | A degeneration similar to mucoid degeneration, in which the material is inspissated. (05 Mar 2000) |
| mucinoid degeneration | A term including both mucoid and colloid degeneration, the essential cellular changes in both being similar, the only difference being that, in colloid degeneration, the substance is firmer and more inspissated than in mucoid degeneration, in which it is thin and jelly-like.
