Juvenile breast hypertrophy: report of a familial pattern and review of the literature.

Juvenile hypertrophy of the breast is a relatively rare condition rapidly leading to gigantomastia in peripubertal females. The pathology is limited to the breast, with otherwise normal growth and development. We have reported the first familial pattern seen in this unusual condition. Ablation of the breast is always required. We favor reduction mammaplasty to avoid breast implants, despite the need for additional procedures secondary to recurrent hypertrophy. Our second patient provides support for this approach, demonstrating amelioration in breast growth despite the initial period of rapid regrowth.
