The corpora amylacea ("bodies of starch") are a histologic finding, encountered more frequently in the brain, prostate, lung, and uterus. The corpora amylacea are thought to be sulfated glycosaminoglycans 1. Some have described it as a localized amyloidosis 2.
In the prostate they appear to arise partly from prostatic secretions and may calcify (in the form of hydroxyapatite) 3. After calcification they can become visible on imaging. Inflammation, possibly from bacterial infection, is theorized to be a factor for their formation in the prostate 3.
