Popcorn calcification within the breast
Popcorn calcification in the breast is the classical description for the calcification seen in involuting fibroadenomas which, as the name suggests, has a popcorn-like appearance.
Pathology
A fibroadenoma in the long run may degenerate and calcify. Initially there are a few punctate peripheral microcalcifications. These, with time, become more dense and coarse finally giving rise to the classical popcorn appearance.
