corpora amylacea
small basophilic, periodic acid–Schiff–positive, hyaline masses, 5–50 μm in diameter, derived from degenerate cells or inspissated secretions and consisting of a central nidus surrounded by concentric lamellae. They occur in the prostate, neuroglia, and pulmonary alveoli and become more numerous with advancing age; their significance is not known. Called also amylaceous bodies or corpuscles, amyloid bodies or corpuscles, and colloid corpuscles.
