{{confused|Corpora arenacea}}Corpora amylacea (CA) are small hyaline masses of unknown significance found in the prostate gland,[1] neuroglia,[2] and pulmonary alveoli.[1] They are derived from degenerate cells or thickened secretions and occur more frequently with advancing age, and are particularly profuse in neurodegenerative diseases.[1] While their significance is unknown, they can be used to identify these organs microscopically. A report published in 2017 suggests a role of debris clearance for the CA.[1] This was described in an earlier report as a debris disposal system.[6]

In the brain, corpora amylacea are contained in foot processes of astrocytes and are usually present in sub-pial location and around blood vessels.{{citation needed|date=August 2017}} In comparison to prostatic corpora amylacea, these are only faintly laminar and less eosinophilic. The major constituent has been shown to be amyloid in humans[1] and the CA in other species are known as polyglucosan bodies.[3] These bodies have no known pathologic correlation{{Citation needed|date=December 2016}} and can be confused with fungal yeast forms such as cryptococcus{{Citation needed|date=December 2016}}.

In the prostate, where they are also known as prostatic concretions, they usually appear in benign glands; however, their presence cannot be used to exclude cancer.[4]
