Galactocele in a prepubertal girl: case report

Galactocele is a rare, benign cystic breast lesion that usually occurs in breastfeeding women, less frequently in children, and more frequently in boys. We report a rare galactocele case in a 2-year-old girl with a painless unilateral breast mass. Imaging was consistent with a cystic lesion, and surgical excision confirmed the diagnosis. Galactocele in this case runs contrary to the male predominance reported in the literature. We discuss the importance of galactocele in the differential diagnosis of breast masses and emphasize its management with monitoring, aspiration, or surgical excision. The etiology remains unknown although it seems to be multifactorial.
