Popcorn-like calcification of the breast

Last revised by Ryan Thibodeau on 6 Jul 2024

Popcorn-like calcification of the breast is the classical description for the calcification seen in involuting fibroadenomas, which, as the name suggests, have a popcorn-like appearance. 

If the calcifications in a fibroadenoma are small and abundant, they might resemble malignant-type calcifications, necessitating a biopsy.

Pathology

A fibroadenoma may eventually 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.
