Corpora amylacea (CA) (from the Latin meaning starch-like bodies) is a general term for small hyaline masses found in the prostate gland, nervous system, lung, and sometimes in other organs of the body. Corpora amylacea increase in number and size with advancing age, although this increase varies from person to person Corpora amylacea in the prostate are a frequent finding in benign acini, but are only rarely observed in adenocarcinoma. To determine the incidence and comparative histopathology of this finding, we prospectively reviewed all consecutive needle core biopsies (excluding consultations) received at Bostwick Laboratories between December 2001 and July 2003 Corpora amylacea are luminal secretions commonly present in benign prostatic acini, 1, 2, 3, 4, 5 and have also been noted in other organs, including the lung and uterus

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. Corpora amylacea are amyloid bodies commonly found adjacent to damaged prostate epithelium. Little is known about their formation or function. The current study sought to characterize corpora amylacea in prostate tissue and to describe their relationship with clinical, histological, molecular, and lifestyle factors, especially with chronic inflammation which is associated with aggressive disease These lamellated concretions are called corpora amylacea. The word corpus is derived from the Latin word corpus which means a body and amylacea is from the Latin word amylum which means starch or gruel. The clinical significance of the corpora amylacea is not known. They may also be found less commonly in the pulmonary alveoli Corpora amylacea inclusions may grow up to millimeter scale, as shown in Figure 18.10 A, and may be very heterogeneous in size [12]. In extreme cases, their bulk weight may constitute up to one third of the prostate gland. These inclusions were also characterized by typical amyloid features as observed in optical microscopy

Site of 10% of prostate cancer (often ductal carcinoma) Contains moderately compact fascicles of smooth muscle. Central zone: 25% of prostatic volume Surrounds transition zone to angle of urethra to bladder base Site of 5% of prostate cancer Unlike peripheral and transition zones, ducts are large and irregula The corpora amylacea are usually found freely in the alveolar space as concentrically laminated bodies. Electron microscopically they are composed of peripheral fibrils and a central core. With regard to their origin, it is suggested that the bodies are formed by the aggregation of alveolar macrophages or of some protein products Corpora amylacea are luminal secretions thought to be related to epithelial cell desquamation and degeneration. They are commonly present in benign prostatic acini of approximately 25% of men aged.. A characteristic feature of the prostate is the appearance of corpora amylacea in the secretory alveoli. They are rounded eosinophilic bodies. Their average diameter is about 0.25 mm (up to 2 mm). They appear already in the seventh month of foetal development

Calcification of the prostate gland is most commonly caused by benign prostatic hypertrophy or chronic prostatitis. The calcifications can be identified at or below the pubic symphisis. When the gland is hypertrophied they may project above the symphysis Benign prostate imaging by [micro]OCT was characterized by features that include prostatic glands that were separated by large amounts of prostate stroma (Figure 1, A and B), the presence of large amounts of prostatic secretions (Figure 2, A and B), and corpora amylacea (Figure 3, A and B)

Morgagni saw them first in the prostate gland in 1723. Virchow found them later in the brain, spinal cord, at the neck of the bladder, and in the so-called female prostate (delicate tubular glands surrounding the female urethra)

Previous studies have shown that corpora amylacea (CA) in certain organs, including the prostate, lung and uterus, are composed of amyloid. This observation raises the question of whether these amyloid deposits share a common origin or demonstrate the diversity which characterizes other amyloid syndromes Corpora amylacea, also known as amyloids, is the accumulation of dense amounts of calcified materials that are protein based in nature. Corpora amylacea normally affects men who are more senior in age, by this we mean men over the age of about sixty years old

Prostate (histological slide) The hallmark histological feature of the prostate is the fibromuscular stroma in which there are clusters of smooth muscles mixed with elastic fibers.Surrounded by this mixture of tissue are prostatic glands, which are responsible for the production of approximately 27% of seminal fluid.These glands, under the directives of 5-α-dihydrotestosterone (DHT), secrete. The prostate gland is subject to the same pathologic processes that occur in other organs such as the heart. (73%), corpora amylacea (20%), and rings of collagen around squamous islands (40%). Infarcts' distinctive histology must be recognized and distinguished from necrosis resulting from infection and prior cryotherapy,.

Secretory cells lack immunoreactivity with antibodies to high molecular weight cytokeratin. 6 Corpora amylacea are seen in approximately 25% of prostate glands in men aged 20 to 40 years, whereas they are rare in carcinomas. 7, 8 Corpora amylacea are round laminated hyaline eosinophilic structures that may become calcified (eFig. 3.6) Corpora amylacea is found in the prostate. Corpora amylacea in the prostate are usually found in men over 60 years of age. The prostate is a small, walnut-sized gland that wraps around the urethra. These calcium build-ups are usually benign, but can cause problems like pain during urination when they grow too large Corpora amylacea are large, round to oval glycoprotein structures that are found within alveoli in a variety of circumstances. They have been reported to be present in up to about 4% of autopsy lungs and are incidental findings with no.

Corpora amylacea (CA) are glycoproteinaceous inclusions that accumulate in the brain during the course of normal aging and to a greater extent in some neurodegenerative diseases, particularly Alzheimer's disease (AD) (Mrak et al., 1997; Keller, 2006; Song et al., 2014) Dense connective tissue and smooth muscle that makes up the bulk of the prostate gland corpora amylacea (prostatic concretion) Prostatic concentrations that accumulate over time in the lumen of lumens of the prostate of aging male Histologically, the calculi appear stratified in concentric layers resembling calcified corpora amylacea. Prostatic calculi appear to form by the consolidation and calcification of corpora amylacea or by calcification of precipitated prostatic secretions or both The affected lobe (s) should be identified if possible and indicated in the tissue identification (e.g., prostate, ventral lobe, epithelium hyperplasia, mild). If paired lobes are affected, the diagnosis should be qualified as bilateral and the severity score determined by the more severely affected lobe
