Light micrograph of a corpus amylaceous (pleural: corpora amylacea), which is a small body found inside prostate glands. The corpus amylaceous is purple-blue, round and has a lamellated (layered) appearance as well as several cracks. The gland in which this corpus amylaceous is contained can also be seen, as well as the pink fibrous tissue surrounding the gland containing the corpus. Corpora amylacea are often seen by pathologists trying to diagnose diseases by examining prostate tissue microscopically. The presence of corpora amylacea is completely normal and does not itself indicate any particular disease. Haematoxylin and eosin stained tissue section. Magnification: 200x when printed at 10cm.
