The patient was a young girl of fifteen and a half years.

After a cold bath, just as the menses were appearing, it was found that the breasts were rapidly increasing in size; she was subsequently obliged to leave service on account of their increased size, and finally the deformity was so great as to compel her to keep from the public view.

The circumference of the right breast was 94 cm.

and of the left 105 cm.; the pedicle of the former measured 67 cm.

and of the latter 69 cm.; only the slightest vestige of a nipple remained.
