Persistent hyperprolactinemia and bilateral galactocele in a male infant: case report

Galactocele is a benign breast lesion, usually occurring in nursing women. This lesion is a rare cause of breast enlargement in
children. In this paper we describe the case of an infant with hyperprolactinemia (which persisted throughout 15 years of clinical
observation) and bilateral galactocele.We speculate that a congenital midline defect in our patient might have impaired the normal
dopaminergic inhibitory tone on pituitary lactotroph cells, thus leading to an increased prolactin secretion by the pituitary gland;
this, in turn, might have favored the development of the galactocele.
