Subcutaneous mastectomy for juvenile hypertrophy of the breast: report of a case.

Massive juvenile hypertrophy of the breast in a 12-year-old girl was successfully treated with a primary subcutaneous mastectomy and secondary placement of gel-filled silastic implants. The patient weighed 114 pounds and her breasts weighed 15 1/2 pounds. Small foci of regrowth occurred at the lateral ends of the mastectomy incisions only; a total of five of these foci were removed. Six years later no evidence of further residual breast tissue was noted and the breasts have been satisfactorily reconstructed.
