Corpora amylacea

Corpora amylacea
Micrograph of corpora amylacea in benign prostatic glands. H&E stain.

Corpora amylacea, also known as prostatic concretions, are small hyaline masses of unknown significance found in the prostate gland, neuroglia, and pulmonary alveoli. They are derived from degenerate cells or thickened secretions and occur more frequently with advancing age. While their significance is unknown, they can be used to identify these organs microscopically.

In the prostate, they usually appear in benign glands; however, they cannot be used to exclude cancer.[1]
