FNAC of Crystallizing Galactocele: Case Series of a Rare Entity With Review of Literature

Galactoceles are one of the most common non-neoplastic breast lesions occurring predominantly in pregnant and lactating women. Long-standing cases of galactocele can crystallize and form a rare entity called crystallizing galactocele. We report two cases of crystallizing galactocele. The first case is a 21-year-old female who presented with bilateral breast lumps for 1 year, which was diagnosed as left breast crystallizing galactocele and right breast as inflamed galactocele. This is the first reported case with synchronous presentation of crystallizing galactocele and inflamed galactocele in the same patient. The second case is a 19-year-old female who presented with a painless right breast lump for 2 weeks, for which FNAC turned out to be crystallizing galactocele. To the best of our knowledge, to date, there are only 21 cases of crystallizing galactoceles published in the English literature.
