Answer

Prepubertal and peripubertal developmental breast lesions may include abnormalities of embryology and gynecomastia.

Abnormalities of embryology include polythelia (accessory nipples) and polymastia (supernumerary breasts).

Gynecomastia is characterized by excessive development of breast tissues in males. It can be physiologic or pathologic in teens.

Neonatal breast hypertrophy is a common transient condition that results from elevation of maternal hormones, seen in up to 90% of all newborns.
